He was Arsenal's player of the year last year. I know that's a bit like being the fastest white guy in the 100m sprint but he has been a key player for them - when fit. That's the continual problem with him, because otherwise he's a dangerous attacking threat from midfield. He's had four 40+ game seasons for Arsenal out of ten seasons, but you could easily argue that we don't need him to play that many games for us.
On a personal level I'd like to see a Welsh player play for us, but generally I'm indifferent to his arrival.
