Arsenal manager Arsene Wenger admits his only regret about signing Petr Cech is that he didn't do it when he had the chance in 2004.
The goalkeeper has been a revelation for the Gunners since joining from bitter rivals Chelsea at the beginning of the season and set a new Premier League record of 169 clean sheets following his shutout against Aston Villa last weekend.
And, Wenger has now revealed he had the chance to snap up the keeper from Rennes some 11 years ago, only to see him eventually move to Chelsea.
And, speaking ahead of Monday's crunch encounter against Manchester City, Wenger said: "I think he has brought his experience and his calm and his leadership as well.
"Sometimes it comes to my mind that it makes me just think that I missed him when he was at Rennes, and how that could have changed for us if we had signed him in that period.
"What I say could be a bit detrimental to David Ospina, and I don't want to be because he was exceptional last year, but Petr Cech, he has done it all.
"He is someone who gives you an aura, a charisma that is always important in the big games for the players.
"You always look around you in the dressing room before a big game and you think, 'Are we strong enough?' And these kind of faces helps you to believe it.
"He went to Chelsea from Rennes and we could have been quicker maybe on the day than Chelsea. Especially because I know his agent very well."
