'Chelsea have had lots of attention for their 4-3-3 system and the way their wide players give teams problems but Manchester United showed that they can do the same thing. Cristiano Ronaldo and Wayne Rooney caused Aston Villa a lot of trouble by roaming all over the place and running at people.
Villa put up a good show and there were a lot of good individual performances but they never knew where Ronaldo and Rooney were going to turn up - just as teams do not have a clue where Chelsea's Arjen Robben and Damien Duff are going to pop up - and that made life hard for their defenders.
With every other team that play 4-5-1 you know 90% of the time where their wide men are going to be. That was the case with Gareth Barry and Nol Solano in Villa's set-up, so United's full-backs could quite easily find those two, get tight and leave their centre-halves two on one against Juan Pablo Angel. But Rooney and Ronaldo move about and step infield a lot.
When they came inside it caused Villa real problems because no one was sure how to deal with it.'
