Ronaldo has abetter midfield of playmakers than Messi does. In the team Messi IS the playmaker AND the lead striker. All teams have to do stop argentina is what they did the last time. Gang up on him. Once you stop his distribution Argentina lack any creativity.
Portugal is not that way. Putting Ronaldo in the wings along with Coentrao is the trump card, Joao Moutinho is a fantastic playmaker, if he is marked well (which wont happen as teams concentrate more on Christiano) then Portugal has a problem. Portugal's weakness is simply their mental ability. You need a team like old fashioned Greece or vintage Italy and they will be destroyed. They have to be frustrated as they only play on the counter. And the longer the match drags on and if Christiano doesnt get space, they start panicking and playing rough.
