That was meant tongue in cheek obviously but the point is that if losing Cesc, Nasri and Clichy results in us being set back 2-3 years of our 'progression', it makes little difference as our 'progression' is pretty much flat. Have we shown remarkable or even noticeable progress in the last few years? I don't think so. Maybe Cesc, Nasri and Clichy have been all that have been keeping us in the top 4 but I don't really think that's true. Wilshere is the new Cesc and to be honest, it's an improvement - maybe not in pure footballing class but (IMHO) certainly in spirit, directness and aggresiveness. Nasri is a massively talented footballer but is he a winner? He's oft-injured and not completely dependable when it matters. If he stays, fine. But he will not be the engine of our success. He might be one of several spark plugs but spark plugs can be replaced. And Clichy does as much harm as he does good.
Look, if all three of these guys were deeply committed to winning with Arsenal and were being sold against their wishes I'd be seriously depressed. But they want to go and they are replaceable. Whether they are appropriately replaced is the question at the fore front of my mind.
