If only Juan Mata 's Manchester United career was as extravagant as his arrival in Manchester, there is no telling what the club could have achieved.
There were more than just a few eyebrows raised when Man United, then managed by David Moyes, swooped to seal a £37.1million deal for Mata from rivals Chelsea in January 2014. At 25, he arguably had his best years ahead of him and perhaps it was only Jose Mourinho who couldn't recognise his value.
The playmaker had played a crucial role in his first two seasons at the club, but Mourinho's return to west London in 2013 saw Oscar prioritised ahead of the diminutive midfielder. Chelsea fans were unhappy with his treatment by the Portuguese boss, but even more so when the talented playmaker was allowed to leave for Old Trafford. To mark the earth-shattering nature of such a high-profile transfer between two Premier League giants, United quite literally swept Mata off his feet in a luxury chopper, which arrived on the green grass at Carrington.
