Juan Mata's transfer from Chelsea to Manchester United is, if nothing else, one that has shocked and stunned in equal measure.
When it’s considered that the Spaniard was a firm fan-favourite for the Blues, as well as two time Player of the Year at Stamford Bridge, it’s fair to say that not many supporters of the west London side would have predicted he would join one of their biggest rivals.
It does however serve to prove that in the modern game anything can happen, and there really isn’t an untouchable player left, so to speak.
