Isn't it just that, a coincidence? Lacazette and Griezmann being friends doesn't mean anything, they're just friends. As much as we speculate that footballers being friends influences a transfer, in reality it's probably the very least influential factor. In terms of convincing Özil to stay, I suspect that he's mature enough to not be swayed just because his mate has come. If he stays, it'll be because he's happy to stay in London, happy with the terms of the contract and happy with the club's vision. I agree that I'd rather Özil stays than spend 60m on a replacement - however much I'd love to see Fekir here - because there are other areas of the team that need attention. If we can get Özil to stay, bring in two good wide players and try to do something about the defence, then overall we should be better off as a team.
