What price a familiar face coming back to haunt Manchester United?
Back in 2012/13, Sir Alex Ferguson’s final Champions League campaign at the helm of Manchester United was brought to an abrupt halt by Real Madrid at the round of 16.
The man to deliver the knockout blow was one Cristiano Ronaldo, with a former Old Trafford favourite returning to his old stomping ground to dash the dreams of those who once idolised him.
A similar story could be about to unfold in 2015/16.
We are not talking about club icons here, but United will be all too aware that familiar faces could come back to haunt them on European football’s grandest stage.
