Alexis Sanchez looked like one of the best players in the world during his time at Arsenal, although things didn't really work out for him once he made the switch to Premier League rivals Manchester United.
The Chilean netted 80 goals and bagged 45 assists during his time at the Gunners, but managed to find the back of the net just five times, setting up his teammates on nine occasions for United.
Sanchez' time at Old Trafford was shortlived as he failed to justify being given the iconic No.7 shirt and he moved to Inter Milan just a year-and-a-half after signing for the Reds.
The forward's time in London, however, was rather different. Sanchez enjoyed three-and-a-half successful years at the Emirates Stadium, winning two FA Cups with Arsenal.
