4. Robin van Persie: Arsenal to Manchester United

Manchester United v Everton - Premier League

Robin van Persie stunned everyone in England when he decided to leave Arsenal after eight long years to join Manchester United in 2012. The Dutchman joined the Red Devils for a reported fee of €30.7 million.

Van Persie was the captain of Arsenal back then and his departure to their arch rivals unleashed the wrath of fans. The player claimed that the chance to work under Sir Alex Ferguson motivated him to make the switch.

The 36-year-old scored 26 goals in the Premier League in his maiden season at Old Trafford. He was quite vital to United's successful campaign as they lifted their 20th Premier League title.

His time at Manchester United was reasonably successful as he scored 58 goals in the 105 appearances he made for them before leaving the club in 2015.
