Don't want to sound bitter, but since Arteta knackered his knee at Newcastle (March/April 2009??), you could probably count the amount of games he has had a lasting influence over, on the fingers of one hand......And this is a guy many Arsenal fans are presently wetting themselves about on Twitter and the like??
I honestly believe we have seen the best of the fellow, and it will be hell of an ask for him to take over the mantle of Fabregas/Nasri.
For Everton, its a healthy profit on a bloke approaching 30, takes a big earner off the wage bill, and, most importantly should finally give Jack Rodwell the huge kick up the backside he needs to prove he can actually hack Premier League football.
