Cech has found himself on the sidelines this season, losing his place to Thibaut Courtois following the Belgian’s arrival from Atletico Madrid.
The 32-year-old has made just one Premier League appearance this season - ironically, against Arsenal - and, whilst he has appeared regularly in the Champions League and League Cup, he is said to be keen on leaving the club in January in the search for first-team football.
Real Madrid, PSG and Besiktas have all been linked with the Czech international, but, most recently, the 10-year servant at Stamford Bridge is reportedly close to agreeing a deal with London rivals Arsenal - for a fee of just £7 million.
It would be a great piece of business for the Gunners, with Cech still one of the top five goalkeepers in the world, and, although first-choice stopper Wojciech Szczesny is reliable, he is hardly the player that could lead the club on a race for the Premier League title.
However, he is something of a fan favourite at the Emirates, and it is unlikely that Arsenal fans would be keen on seeing their stopper replaced by such a legend of Stamford Bridge. Cech would undoubtedly command a starting role for the Gunners, but former Chelsea and Manchester United goalkeeper Mark Bosnich believes that Szczesny could benefit from the signing of the 32-year-old - as it would give the Polish international competition and a need to improve.
Speaking to talkSPORT, the former Australian international said: “Put it this way, it will either be the making or the breaking of him.
“As a player, when we look back we think maybe we played our best when we did have competition. At the time you think that when someone comes in for your position, ‘did you have to do that’, but it depends on his [Szczesny’s] trust in the manager.
“He just has to make sure he performs week in and week out.
“Even if Cech comes he will still stay in the side unless he’s having a bad time. [He needs to] keep on his toes, that’s the best thing to do.”
It has been widely reported that the keeper has come close to agreeing a deal with Arsenal, and it will be interesting to see if Szczesny ups his game in the coming weeks to prove that he should be the Gunners number one.
