Hard to reply on an iPhone so I'll keep it short - yes he seems a mercenary to me, and as much as you may not like it, it is pretty indisputable that he would have created a lot of interest for whichever club signed him. Hence, losing him is not a good thing. If he was after the money though, then eh, he'll probably be back in a year. I was mostly hoping to sign him so that we could actually have our first 'star' recruit in years.
If he signs for another club I don't care anymore.
By the way, four weeks is actually long for someone that would obviously want his future settled, particularly when teams are really getting into the pre season there.
