Goal keeper Petr Cech has completed his move from Chelsea to Arsenal. Cech has also written a letter to Chelsea fans, admitting he thought he would “finish his career” at Stamford Bridge. However, after losing his starting position to Thibaut Courtois, he says he had to move on for “new challenges” because he is not at the stage of his career where he is happy to sit on the bench. The Czech adds that he “couldn’t be more proud” of what he achieved during 11 years at Chelsea but it is “time to begin a new adventure”. Arsenal boss Arsene Wenger says Petr Cech is “one of the outstanding keepers in the world” after the Czech joined the Gunners from Chelsea for an undisclosed fee. The 33-year-old made over 400 appearances during 11 years at Stamford Bridge, winning every major club honour at least once and the Premier League Golden Glove award on three occasions. “Petr Cech is a player that I have admired for a long time and I am very pleased that he has decided to join us,” said Wenger. Cech added: “When Arsene Wenger spoke to me about his ambitions for this club, and how he saw me as part of this team, the decision was clear.”
