Joseph Yobo hailed Everton matchwinner Tim Cahill after their victory at Manchester City.

The Nigeria defender told evertonTV: "Tim is an invisible player because he is so difficult to mark - he is a nightmare for defenders to play against.

"You don't know whether he is a striker or a midfielder and when he gets a chance like he did at City, you always back him to take it.

"You have got to give him great credit because he played up front on his own. He carried the fight to City and spurred us on. He's a very important player and he has shown that once again.

"He is a fighter. Even when he doesn't play in his best position, he gives everything for the team and he sets an example."
