Everton defender Joseph Yobo has been speaking about the positive impact that Tim Cahill has made to the team since his return from injury.

Cahill scored a last gasp winner in the recent game against Manchester City and Yobo reckons that Cahill’s ability to arrive in the penalty box at the right time gives the team a massive advantage.

Yobo said “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”.

Cahill has now spent four years at Everton, having signed for David Moyes’ side from Millwall in 2004. Currently he has made 112 appearances and scored 32 goals.
