Chelsea have been offered the chance to re-sign Petr Cech as they ready themselves for a Real Madrid raid for Thibaut Courtois.
The Stamford Bridge club are also interested in Kasper Schmeichel and Gianluigi Donnarumma amid expectations that the Belgian will leave west London this summer.
Arsenal are open to selling Cech to provide manager Unai Emery with the funds needed to continue rebuilding his squad.
The veteran goalkeeper has already turned down a move to Napoli to stay at the Emirates and fight for his place with new arrival Bernd Leno.
Cech spent 11 seasons at Stamford Bridge, winning the Premier League four times and the Champions League.
