You missed my point, but hey it's a kind a habbit to you. You were speaking about effort, so look it up. And man you can only pitty yourself.
the example of rooney, ronaldo, messi failing to show at the world cup whilst tevez did only shows that tevez is indeed a big game player, that is not to say the 3 previously mentioned are not cause they have showed it in other examples, but to say tevez is not a big game player is truely absurd.
