Can't see why Citeh need to buy him personally. Doesn't add up for me, especially as they're looking to trim their squad.
That said. If someone did offer £20m (which I highly doubt anyone will) and he left, then I'd wish him all the best.
Good player, seems like a decent lad; needs to grab hold of a first team place and start bossing games sharpish for me though.
Look at the facts. We need to sell to buy. It doesn't make us a feeder club, or a selling club, or a second rate club. Every club, barring Chelsea, Man City and Man Utd have to sell assets to reinvest. Arsenal's oft vaunted 'self sustainable' model is reliant on £20m per annum income from player sales, they've admitted as much themselves.
