Lack of world class keeper has held Arsenal back... if Chelsea want £10m, Cech is a must

 
Cech could be an important member of Arsenal's side if he switched clubs 

Jose Mourinho says Cech can leave Chelsea if he wishes, but only for big money as he rates him one of the top three goalkeepers in the world.

So here's the question. If Petr Cech, at 33, is available in the summer, and Arsenal have a chance of buying him, what should be Arsene Wenger's best offer? 

Cech cannot command such a fee at his age. A better marker may be the £9m Liverpool paid for Simon Mignolet. Is Cech better than Mignolet? Yes. So if Chelsea asked for £10m for a 33-year-old reserve, should Arsenal be tempted? Yes again. 

The absence of a world class goalkeeper is holding Arsenal back. Cech could easily last another four years at the top, making him value at £10m. 

Pat Jennings was 32 when he switched from Tottenham Hotspur to Arsenal in 1977; he played his last game for the club in 1985 at the age of 39. There has never been a question over his worth and Cech could be as important.
