Lou Macari picks three areas where the Champions League final will be won and lost...
Rio Ferdinand v Didier Drogba
"This is Rio's best season in a red shirt and his performance on Wednesday could go a long way to helping United win. He'll need to be on his guard against Drogba's antics – I've noticed he tends to go to ground more easily these days. I wouldn't say Drogba is Chelsea's main weapon – Essien, Ballack and Lampard are just as important – but give him a glimpse of goal and he'll punish you as he did in last season's FA Cup final. I've got great confidence in Rio. He has the strength, pace and experience to cope with any forward."
Cristiano Ronaldo v Ashley Cole
"This battle could have a big bearing on who ends the night victorious. Cristiano has had an outstanding season and has the opportunity to really make a name for himself in the biggest club game he'll have ever played in. Ashley Cole lost his way a bit after leaving Arsenal, but he's sharp, quick and good in the tackle. On his day he's a top defender and he'll know that if he can mark Ronaldo out of the game then Chelsea have a great chance of winning. I just hope he has an off day and Ronny is on form."
Wayne Rooney v John Terry
"Few players are as determined and committed to their teams as these two. Wayne is such an important player – he showed that against Wigan, winning the penalty and setting up Ryan Giggs to seal the title. He'll be up against tough John Terry, but Wayne is capable of getting the better of him. There's a height difference, but I've seen Rooney play against taller players than Terry and give them problems. He's intelligent and knows how to play against any centre-half. On the night, Wayne can be as important as Ronaldo."
