The 33-year old has joined the Gunners for an undisclosed fee on a long-term contract.
Speaking to the club site, Wenger was full of kind words for the new arrival:
“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.”
The Czech Republic international also gave his take on the move:
“I’m really excited about joining Arsenal Football Club and can't wait to join up for pre-season. 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 Arsène 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 signing of Petr Cech may prove to be Arsenal’s best piece of business in recent years. The goalkeeping position has been somewhat of a problem position for the Gunners since Jens Lehmann’s departure and the arrival of Cech adds real quality and experience to the backline.
Arsenal’s attacking prowess has been evident in recent seasons but their defending and naivety has been their downfall and has made a sustained title challenge impossible.
The signing of Cech brings not only a world class keeper capable of points-winning saves, but also a wise head to lead from the back and ensure the defensive slip ups, which have plagued Arsenal recently, become a thing of the past.
There is still work to do if Wenger is to create a genuine title-challenging side, namely a top class forward and central midfielder, but Petr Cech is a major step towards that goal.
