Arsenal have signed Petr Cech from Chelsea in a deal worth about £10m.
The Czech Republic goalkeeper, who played more than 400 club games in 11 seasons at Stamford Bridge has joined the Gunners on a four-year contract.
Cech, 33, made only seven league appearances last season after losing his place to Belgian Thibaut Courtois.
In a letter to Chelsea fans, Cech said he thought he would retire at Stamford Bridge, but added: “Life doesn’t always turn out the way you think it will.”
He wrote: “Last summer, things changed and I understood I was no longer the first-choice keeper, but I felt it was not the right time for me to go.
“During the season, it became clear that my situation would not improve and – as I know I am not at the stage of my career where I want to be on the bench – I made my decision to move and look for new challenges.”
