Arsenal FC turnover 2004 was a memorable year for the Gunners (hereinafter Arsenal FC). They won the English Premier League with an unbeaten record. However, after an undefeated season, the Gunners only won the FA Cup in 2005 and have failed to win any major trophy since 2005. The Gunners' turnover problem (which defined player departure) increased continuously after 2004 and the reason that led to the failure was the number of turnovers of the first team. The player turnover was mainly caused by the Gunners' defeat. After 2004, Arsenal FC no longer invested resources to strengthen their squad. They changed their philosophy to develop young people. It hasn't been a problem for a club to develop for the future, however, the Gunners haven't signed some experienced players to lead the youth. It is impossible for a talented player to develop his potential without the help of experienced players. The legendary manager of Manchester United FC, Sir Alex Ferguson, decided to develop young players with the help of experienced players. One of the football stars, Cristiano Ronaldo, was coached by two experienced players, Paul Scholes and Ryan Giggs when he was still a youngster. Cristiano said he would like to thank the mentorship of Ryan Giggs and Paul Scholes when he just arrived at Man Utd on his personal Twitter. When Cristiano Ronaldo joined Manchester United, he was just a cheat. His trick was reprimanded by Scholes and Scholes told him to concentrate on pragmatic football. At the same time, Giggs taught him to analyze the situation on the pitch. Cristiano Ronaldo has become more mature and helped Manchester United win the treble including English Community Shield, English Premier League and Eur...... middle of card ......tar Mesut Özil of Real Madrid CF Mesut Özil helped Arsenal record their best start to a season in a decade and took Arsenal to the top of the table. Due to his arrival, some talented players such as Wilshere and Ramsey have stated that they are willing to stay at Arsenal FC. The turnover of first team players was reduced in 2013. From the above, we can conclude that what Wenger should do is to try to strengthen the team by signing top players in order to reduce the turnover of the Gunners. To summarize, star players can lead the club to success, attract other players to stay or join, and mentor young people. The Gunners should strengthen their squad by signing star players so they can attract players who stay and reduce the turnover problem. I believed that if Arsenal adopted such changes, they could win the trophy again within a few years.
