6. Alexis Sanchez
After swapping Arsenal for United, Sanchez suffered a disastrous stint at Old Trafford with just only five goals to his name.
While things never really improved on the pitch, though, the Chilean struck gold with his lucrative Red Devils contract.
Sanchez is currently on a season-long loan stay at Inter Milan, where he hopes to rediscover his old self.
And even if he doesn’t, the 30-year-old still has a lovely income to pocket.
