He's a true professional GM. Being 100% committed shouldn't be too hard regardless of his thoughts about staying or leaving. Plus he actually loves the club as well. But I don't doubt for a minute that he is not seriously considering his future here, what with our ambitionless and '4th place is all good' ways. If he wasn't, he'd either be one of the greatest legends the club has ever seen, or just a man lacking a personal winning desire. And he doesn't strike me as one to be classed as the latter.
Don't know how I feel about Podolski coming in as his replacement if that's what it's going to be (with us, that's really the more likely scenario).
