Arsenal manager Arsene Wenger told the club’s official website:
“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. He has proven over many seasons that he is one of the outstanding keepers in the world and he will add great strength to our squad.”
“I’m really excited about joining Arsenal Football Club and can’t wait to join up for preseason. I have the same commitment to football, the same motivation and the same hunger for success as I had at the beginning of my career, and I love the challenges brought by the top quality players you face while playing in the Premier League.
“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.”
The Czech Republic international won four Premier League titles, four FA Cups, three League Cups during Chelsea’s sustained era of domestic success and has also lifted the Champions League and Europa League trophies during his time at the club.
David Ospina, who displaced Wojciech Szczesny as first-choice keeper after joining Arsenal last summer, has been linked with a move to Turkish club Fenerbahce. Arsenal would prefer to keep Szczesny over Ospina as Szczesny qualifies as a home-grown player.
