Arsenal legend Bob Wilson has hailed impact of Petr Cech this season

Cech has been outstanding since his arrival from Chelsea last summer.

Writing in his Daily Express column, he said: "I can remember when we won the title at Arsenal in 1971, it was said that I was worth 14-15 points to the team - in the days when it was two points for a win. Cech will be worth more than that.

"His impact on Arsenal and the squad has been massive in the last six months. What he has - and indeed every other great goalkeeper I have encountered has - is an extraordinary presence. Both on the field and off it.

"Pat Jennings, David Seaman, Peter Schmeichel, Gordon Banks, they all had this presence, this aura about them - and Cech has it too. Well by my reckoning as a regular Arsenal watcher, he has already earned them that so far - and by the end of the campaign I expect him to have earned them more than 20 points."
