Arsenal have opened talks with Chelsea about signing Petr Cech this summer.

Fanz Championship understands the Gunners and French champions Paris Saint-Germain have both made official contact with the Blues, who have reluctantly agreed to sell their long-serving goalkeeper.

Cech, who turns 33 on Wednesday, is believed to prefer a move to Arsenal, and a sensational £10million deal between the bitter London rivals is now a growing possibility.

Chelsea boss Jose Mourinho has already admitted he is powerless to stand in Cech's way, and the club are unlikely to block any deal if he wants to move to the Emirates.

That leaves the ball firmly in Arsenal's court and boss Arsene Wenger now has the chance to pull off one of the headline deals of the summer.

The Gunners are keen to sign a new No1 this summer - there are doubts about last summer's £3m buy and current first-choice David Ospina while Wojciech Szczesny is set to leave the club.

Manchester United are also watching developments, with David De Gea likely to leave them for Real Madrid.
