It's been a great summer for the Gunners so far but new boss Unai Emery could be about to make his first mistake as Gunners boss. 

Arsenal brought in Bernd Leno this summer to compete for the first-team spot but according to the Daily Mail, the Gunners are considering letting Petr Cech return to Chelsea.

With Thibaut Courtois rumoured to be on his way to Real Madrid, Chelsea have identified Cech as an adequate replacement and are keen to bring the Chelsea legend, who left in 2015 back to the club.

Chelsea had been interested in a move for Alisson but with the Brazilian now set to join Liverpool, Chelsea have identified Cech as an alternative.

The Breakdown

Arriving for £22.5 million, Bernd Leno was brought in to the squad to compete with Cech and in the long run, take over from the former Chelsea man. Due to Cech's poor performances last season, Arsenal desperately needed to strengthen during the summer. The 'keeper has done well for Arsenal in the past but last season his performances dropped massively as Cech had arguably his worst season for the club but even so, his experience and leadership could be vital next season.

At 36-years-old, it's unlikely that Cech will be at the forefront of Emery's rebuild but the Spaniard could still use him to help bed in Leno and use his experience to help the squad. A Premier League and Champions League winner, Cech is one of the few players in the squad who knows what it takes to win.

His performances may have dropped but Arsenal should keep him to compete with and help Leno.
