What went wrong for Juan Mata at Man United?

He arrived with potential to be the best in the league. Why didn't he reach these levels?

Fantastic player probably at the wrong time. Think he was a bit unlucky that football seemed to move away from classic no 10s in his era

United signed him without a plan where to actually play him! Great player - but he was a panic move after a disastrous summer in 2013

Ironically, how many were we crying out for exactly this kind of creative midfielder in Fergie’s final years
