But hold onto your pants: he doesn't necessarily mean as a player.
On the question of whether he would ever come back to Arsenal, Cesc replied:
Arsenal is in my heart and always will be. I don't know if I'll have the opportunity to go back and play there one day, or maybe after football. It's a club that is always going to be there and will always open its doors to me. The club's like a family so even if it wasn't as a coach, I'm sure they'd give me the chance to play a role. Sol [Campbell] is there now. Arsenal help a lot with the formation of coaches. [Dennis] Bergkamp also went there two, three times a week when he was doing his coaching badges. In that sense it's a lovely club and there might be the chance to do something with them.
So it's possible that Cesc might come back, but perhaps as a coach rather than as a player.
He also mentions that not winning a title with Arsenal will always be one of his great regrets:
[I]n the last few years we [Arsenal] played the most attractive football [in England], entertaining the fans. People enjoy watching them and I'm proud of that. People say: "OK, they haven't won anything but, wow, I'd pay money again to see these boys play." There are other teams that have won more – and I'm not naming names – but when they win people say: "Well they've won but that's all." I'll always have that thorn in my side, though, that sadness. I wish I'd gone with a title.
He also had an interesting perspective of why Arsenal always fell short of winning the title in the last few years, partly because of the young squad being inexperienced, but that the current Arsenal squad seems to have the balance right. Cesc thinks that Flamini and Ozil are spectacular signings.
As for Robin van Persie...
As an aside, it's always assumed that Jack will be Arsenal's future captain, but Ramsey's already been captain of Wales. Could it be that Ramsey is Arsenal's future captain instead? Anyway, the interview is an interesting read, even if it is tinged with the feeling of an amicable ex talking about good old times, and some nostalgic, bittersweet regrets. But it seems as if even that old ex realizes that the ship has sailed. Arsenal have moved on, and have got a new man in Mesut Ozil.
