Portugal playing with 10 men and have been for 3 tournaments. Its an utter joke.
Argentina carry Messi but he is a different personality to Ronaldo and his style of play makes him more affective when he gets the ball. He can still jink past a player and curl it inside the post, he also finds pockets of space and slides passes and crosses that set other players up. He can't run all game, but when he gets it he still has the ability to create magic.
Ronaldo was a powerhouse built on speed, strength, quick feet and aggression. When that strength goes all you have is a bloke standing in the 6 yard box gesticulating because he isn't being given tap ins. Nobody likes him, they can all see it, it embarrassing for all concerned. If you get him the box with the ball he will still score goals, but so would any decent player, but you can't play with 10 every game just to set him up, there are other players who can score those chances who are also contributing in other parts of the pitch and aren't spreading unpleasantness to those around him.
The same with Neymar, why bring on a bloke who can't run anymore, has put on weight and is a total passenger when you have Thiago amongst others on the bench.
They both deserve to be out.
