Just a shame to sell him when he finally has a season where he shows his true potential. They pay him for all those half seasons with injuries and patchy form, only to offload once he starts doing what what they hoped he would the whole time. And to Man Utd too.....
Milan or Barcelona I would have understood, but unless they make a big signing before the end of the window, it's clear they have no serious intention to challenge the Manchester clubs for the title, even if Wenger probably still thinks it's on.
I don't really blame Van Persie, though.
