John Terry is concerned that if Petr Cech leaves Chelsea this summer and signs for Arsenal then the Gunners will be genuine Premier League title contenders next season.

Arsenal are currently available at 5.50 to win the Premier League title in 2015/16, while Chelsea can be backed at 2.38.

The 33-year-old Czech Republic shot-stopper is widely believed to be on the verge of ending his 11-year association with the Blues after losing his place to Thibaut Courtois last season.

Arsene Wenger appears to have won the race to land the former Sparta Prague and Rennes goalkeeper who has made almost 500 first-team appearances for Chelsea.

Terry told radio station Talksport: “There is obviously talk of Arsenal signing Petr and, if they do get him, that will strengthen them for sure. He will save them 12 to 15 points a season.

“I am sure, if he does leave the club, which nobody wants to see but we understand he wants to play football, he is going to be sorely missed. He will improve whatever side he goes to.”

Chelsea are expected to sign Monaco striker Radamel Falcao on a season-long loan agreement this summer even though the Colombia international endured a difficult 2014/15 campaign at Manchester United.

Terry knows that strengthening the squad is the right thing to do though, adding: “To be top of the league the whole way through the season was an exceptional thing to do, but you can’t dwell on that.

“We have to start concentrating on next season and try to improve on that again.”
