Was no controversy as far as I was concerned with their disallowed goal. They had 3 players stood in offside positions and the main one (think it was Goufran) actually had to move out of the way of the flight of the ball. If you have to do that then how can you argue you are 'not interfering' with play. Quite clearly, if you are in the way of the flight of the ball and it is going to hit you, you are offside. Hart is probably anticipating the deflection therefore the Newcastle player affects his decision making therefore he is offside.
As for their tackling and challenges in the second half, well, words fail me, the Nasri challenge in particular was disgusting a sending off every time.
Great result from the lads but the Nasri injury has really put a dampened on the result.
