How do you know we didn't spend money on players because Wenger believed in the young players he had purchased and he didn't want to limit their opportunities? Or perhaps because he thought the market was temporarily inflated by Chelsea and City and that with FFP coming it might be wise to hold off?
Regularly sold our best players, because of the financial constraints of the stadium? I don't think we sold Fabrergas and Nasri because we had to financially, I think we sold them because they wanted to leave a team that wasn't winning trophies and they wanted to increase their salaries. But neither of us really know, do we?
