4) Robin van Persie – Arsenal to Manchester United
With the sale of Cesc Fabregas and Samir Nasri in one transfer window Arsenal looked a broken team only to be dragged almost single-handedly to the top four by Robin van Persie.
The Dutchman was now Arsenal’s captain, their talisman, their player of the year and fans were hopeful he would re-sign after his contract came to a close at the end of the season.
However, that all came crashing down when van Persie released a statement exclaiming he wished to win trophies and didn’t trust he would do so at Arsenal before promptly signing for Manchester United.
It can’t have been nice for Gooners to then see the Dutchman get his wish in his first season winning his first Premier League for the Red Devils, not Arsenal.
