The Czech Republic international completed a move to Emirates Stadium from rivals Chelsea on Monday after falling behind Thibaut Courtois in the Stamford Bridge pecking order - the 33-year-old signing a long-term deal with the Gunners.
However, Cech could have been first choice at Arsenal much sooner had their original move for him in 2002 gone through, with the goalkeeper instead leaving Sparta Prague for Rennes, before arriving at Chelsea for what became a memorable 11-year stint.
"There was a chance before I went to France [to join Rennes] that I could sign for Arsenal but I was only 18 or 19 and, at that time, Czech Republic were not in the European Union," he told the club's official website.
"You needed a work permit and the conditions were to play 75 per cent of the first-team games for the national team, which, at the time, was impossible for me to get. In the end I went to France because I couldn't get a work permit.
"I had a few teams who were interested but Arsenal was one of the main ones. I was so excited because of the Premier League and big clubs but unfortunately it was not the time for me to come.
"It was later with Chelsea, and I'm obviously grateful for that, but you can never prepare the ways in your life and you’ll never know where you'll end up. Here we are and I hope that I can replicate all I've managed to achieve in the past decade.
"If I could have got the permission, maybe my story would have been a completely different story but here we are 10 or more years later, and now we can write the story again."
