This article will provide you with some professional guides to help you find the best football.

1. Material: The material of football is mainly divided into leather and synthetic materials. Leather football is usually more durable and feels better, but the price is also higher. Synthetic football is cheaper, but it may not be as durable as leather football. You need to choose the right material according to your budget and frequency of use.

2. Size: The size of a football is usually marked by its diameter. Generally speaking, the diameter of a standard match ball is 21.5 cm. However, for beginners, it may be better to choose a bigger football because it can help them control the ball better. If you are an adult or a teenager, you can choose a smaller football.

3. Weight: The weight of football is also very important, because it will affect your performance in the game. Generally speaking, the standard football weighs about 410 grams. If you often train for a long time, then you may need to choose a heavier football.

4. Brand: There are many well-known football brands in the market, such as Adidas, Nike and Puma. These brands of football have certain quality assurance, but also have their own characteristics in design. You can choose a brand according to your personal preference and budget.

5. Price: The price of football varies greatly, ranging from tens of yuan to hundreds of yuan. Although the higher the price, the better the quality of football, but you don’t need to spend a lot of money to buy a good football. Generally speaking, 100-200 yuan football is enough to meet the needs of most people.

6. Test: Before you buy a football, you’d better try it yourself. You can try a few kicks on different courts to see how the ball feels. In addition, you can also ask your friends to try it and listen to their feedback.

Generally speaking, it is not difficult to choose a good football. The key is to choose according to your own needs and budget. I hope the above suggestions can help you.

American men’s basketball team loses sparring, making it awkward. Cunningham plays Dancsics and dominates the audience.

As the Olympic Games will be held in Paris next summer, many active American basketball superstars are unwilling to spend too much energy in the upcoming basketball World Cup in Asia this summer. Looking at the lineup of the United States team in this tournament, the younger generation of Edwards and Ingram are already the most famous players, which is a lot dimmer than the 2019 China Basketball World Cup.

Yesterday, the American men’s basketball team was assembled, and today, the first match with the American men’s basketball team was completed, and the result was not satisfactory. According to American media reports, the sparring team led by Cunningham finally defeated the home team of the American men’s basketball team 47-39 in this 20-minute team training match. It is reported that Cunningham played well in the game, Jay Green was efficient in Zhuo Qun, and Durham also dominated the rebound with his figure advantage.

However, for such a result, coach Cole, who is about to lead the American men’s basketball team to the World Cup, is not worried. "This is a long-standing tradition of the American men’s basketball team. Everyone knows what grant hill and Bob Hurley did in 1992. In 2019, the last World Cup, the sparring team also kicked the ass of the team. This is the point. You want the best players to join the sparring team to challenge you, which is exactly what the sparring team did today. " Cole said in an interview.

Besides Cunningham, this year’s American men’s basketball team also includes young players like Jay Green, Holmgren, Trey Murphy and Keegan Murray. It is worth mentioning that Halliburton, who is about to represent the United States in the World Cup, also led a team to defeat the United States team that won the Tokyo Olympic gold medal in training camp in 2021.

One of the most concerned issues about this American national team is what kind of starting lineup Cole will have. According to reports, in order to keep it as secret as possible, the first five minutes of the training match were not open to the American media. Besides, the reporters didn’t get any personal data about the players in this training match. However, sources inside the team revealed that Cole’s five starters in this training match were Ingram, bridges, jaren jackson Jr., Bronson and Cameron Johnson. Cole said in an interview that the lineup used in the training match has nothing to do with the final start.

Interestingly, Cole had clear requirements for the way the United States selected sparring teams before the game. During the dialogue, he expressed the hope that Cunningham could imitate Dancsics’s core play of holding the ball, and launch more tactics through high-position pick-and-roll. Thus, the Slovenian men’s basketball team led by Dancsics has become the number one imaginary enemy in Cole’s mind.

French media: Frankfurt, Wolfsburg, Leipzig and Leverkusen intend to introduce Ekitik.

Live on May 21st According to Goal, Frankfurt, Wolfsburg, Leipzig and Leverkusen are interested in introducing Ekitik.

According to reports, Ekitik can’t get enough playing time in Paris Saint-Germain, and Campos hasn’t yet made clear the future of Ekitik. Ekitik’s first season in Paris was complicated and received a lot of criticism, but he was still very concerned in the transfer market, especially in the Bundesliga.

It is reported that Frankfurt has been paying attention to Ekitik since he played for Reims and has made several contacts with his agent in recent weeks.

In addition, Wolfsburg, Leipzig and Leverkusen are also paying close attention to Ekitik. However, no team has made an official offer yet, and Ekitik also needs to evaluate his future after the end of the season.

Tianjin women’s volleyball team beat Beijing 3-1! The championship game is getting weaker and weaker, and Wang Baoquan may be able to give it a try.

In the final of Jiashan Division of the National Women’s Volleyball Championship, Tianjin Women’s Volleyball Team fought Beijing Women’s Volleyball Team again. In the first two meetings, Tianjin Women’s Volleyball Team won Beijing Women’s Volleyball Team 3-0. When they met again, the outside world was almost optimistic that Tianjin Women’s Volleyball Team could beat Beijing Women’s Volleyball Team 3-0 again and win Jiashan Division easily.

As soon as the game started, the performance of Tianjin women’s volleyball team was unexpected. It played back and forth with Beijing women’s volleyball team. Beijing women’s volleyball team even pressed Tianjin women’s volleyball team to play, and Beijing women’s volleyball team finally won the first game with 25-21. In the second game, the two teams were still relatively deadlocked at the beginning. Tianjin women’s volleyball team made a strong effort in the game, opened the difference and won the second game with 25-16; In the third game, the second team started again, but Tianjin women’s volleyball team made great efforts in the second half and won the third game with 25-20. In the fourth game, the Beijing Women’s Volleyball Team stopped the Tianjin Women’s Volleyball Team at the beginning, but after the time-out, the Tianjin Women’s Volleyball Team quickly overtook and opened the difference, and finally won the fourth game with 25-17, defeated the Beijing Women’s Volleyball Team with 3-1 and advanced to the finals.

Looking at the championship, Tianjin women’s volleyball team is getting worse and worse compared with Beijing women’s volleyball team. They could easily beat Beijing women’s volleyball team 3-0 before, but they played harder and harder in the later stage of the championship. Why? In fact, it can be said that the shortcomings exposed by Tianjin women’s volleyball team in the championship have not been improved, and Wang Baoquan seems to have no way, which makes other teams keep marking time under the condition of continuous progress. As the saying goes, if they don’t advance against the current, they will retreat. Tianjin women’s volleyball team naturally becomes more and more weak at the end of the championship, and it is more and more difficult to play the leading edge at the beginning.

And what are the problems exposed by Tianjin women’s volleyball team? Why can’t Wang Baoquan solve it? In fact, the short board of Tianjin women’s volleyball team is obvious, that is, the pass and the attack are not balanced. Because WangYiZhu doesn’t pick up the pass, Chen Boya has to take care of the attack in six rounds. Yang Yi is an important part of the Tianjin women’s volleyball team’s pass system, but when Chen Boya picks up the pass in six rounds, the attack is obviously affected, while Yang Yi’s pass is stable, but the attack is quite bad. In addition, her appearance on the court has caused the lack of attack at the No.2 position of Tianjin women’s volleyball team.

And why did Wang Baoquan fail to solve the problems exposed by Tianjin women’s volleyball team after so many games? The reason is that his hands don’t have many cards available. Except WangYiZhu, Chen Boya, Yang Yi and Liu Meijun, Dong Mingxiao and Liu Xin obviously can’t meet the requirements of Tianjin Women’s Volleyball Team. Dong Mingxiao didn’t pass, and the attack was not particularly strong. What about Liu Xin? In the few minutes before playing, although she took on a pass, she didn’t catch it well, and she didn’t have outstanding offensive strength. She was not as good as Chen Boya and others, and Wang Baoquan was somewhat conservative in ranking and disposal, and she didn’t dare to let WangYiZhu take a pass, nor did she dare to let Yang Yi change to a free man, which made the Tianjin women’s volleyball team fall into great difficulties.

For Tianjin Women’s Volleyball Team, it is difficult to make up for the shortcomings exposed by routine employment, and it is also difficult to improve in a short time by relying on the players’ self-improvement. Perhaps Wang Baoquan can give it a go and let Yang Yi play as a free agent, and WangYiZhu and Chen Bo Jacob will take a pass in three rounds, which may have unexpected results.
