You got a point there.. Mata always play bad against City I feel.. its like he's too small and when given proper marking on him he cant seem to do much, he needs freedom. I'm no tactician but there must be a way, a certain tactic that could get Mata free, cause when this guy has freedom... Oscar just doesnt fit in the wide position he is given, he should be more of a linking man between the defence and Hazard\Mata\Torres\Ba. I feel like he would work in a more of a middle position, but seems like Mata already took charge of that position. And another thing about Oscar, he showed good fighting spirit and will to win!
