Ben Hibbs: The focus may be on the Reds' big names – Robin van Persie and Wayne Rooney – or the man making his 1,000th senior appearance, Ryan Giggs (possibly a shrewd, rousing selection by the boss). But I think the in-form Carrick is the key man. Real Madrid are at their most potent on the break, so United cannot go all-out attack. Neither can the Reds sit back and invite pressure. As always in Europe, keeping and controlling possession is important. That’s what Carrick does best, and he’ll need to be at his very best on Tuesday for the Reds to get through. His form suggests this is his time to rule on the big stage. Here’s hoping, anyway.
