He told the official Arsenal magazine: "We knew that Kolo hadn't been 100 per cent happy at the club for a few months, and it's not the first summer that we'd read Ade was going to leave,' said Clichy, who may be one of a number of players rested for tomorrow night's Champions League play-off second leg against Celtic as Arsenal hold a 2-0 advantage.
"I think it's a good challenge for them - if they can do well with a good team then it's nice for them. Of course people are talking about other clubs' signings, but it's like this every summer. You have one team spending big money, and of course people will talk about them because you need to discuss something before the season has started.
"But for many years we've seen that clubs can spend lots and not win anything big. It shows you that it's not always about money - of course you can always bring more players and experience in, but I think we have a really good squad here.
"If all these players stay fit then, with the addition of Thomas Vermaelen, I think we have a great squad. And I'm really not saying that just for the sake of it - I feel that we have a good, strong team and we will show everyone what we can do this season."
