Of course. I never disputed that. The thing you fail to understand is it is more that enough to judge whether he was professional or not.
We will just agree to disagree, which I have no problem with. I just don't know how a fan can call a footballer severely unprofessional, uncommitted, ill disciplined and whatever else you called him without being privy to any inside knowledge or working with the player. You, like any other fan don't how much work he puts in the gym, how well he looks after himself, how much work he does individually, how much ambition he has, what his personal goals are, whether he is happy or not etc and yet with only a couple minutes a month you have more than enough to decide on his professionalism.
I'm not sure how he would have led his team to a league victory in the Eredivisie, be the best player in the league, make the WC squad and do reasonably well enough to earn a move to Manchester United. But after 9 months under LVG you have concluded on your opinion. Each to their own.
