Four home-grown players Chelsea could demand from Arsenal as part of Petr Cech deal

4. Wojciech Szczesny

Could it simply be that the London rivals swap number-two goalkeepers? Szczesny has insisted that he is staying with the Gunners, but Arsene Wenger may have other ideas after a few discipline issues.

Mourinho is not one to entertain off-field drama either, but will need a deputy for Thibaut Courtois should Cech leave and Poland international Szczesny would add to his thin home-grown quota.
