Fair point...but it would be frustrating to play in a position which isn't working for you, when things are going wrong for the team. I had to play left back once, and hated it. The team were playing sh*t...we lost about 13-3. I did indeed try my best, but I played awful, and yes, was pretty frustrated that I could not play in my proper position...I'd be annoyed if I was slated for my bad performance in an unfamiliar position though.
I take your points...his loss of concentration and determination is disappointing. He does need to indeed grow up a bit. But don't you even see my point of playing him is his proper position at all? IF and that's a big IF...he plays there, and continues to play badly...then you are clearly right, and he is no good for this league. But until then, I don't think that can be decided.
Of course I can, being played out of position doesnt help your performance - for sure.
What I think you are finally coming to terms with is that I am not critiquing him soley for playing less effectively (which he could be forgiven for by his being out of position). My biggest bugbear with him is the unprofessional way in which he goes about it. The rolling on the floor, the waving arms, the poor choice of outcome when he has the ball. Something that any player of his age should know isnt on.
When - ala Di Canio - you are scoring for fun, rippining it out of players, and winning games for your team, people - not me, but most people - will forgive your petulance. Not when (whether you are being played in your correct position or no) you arent cutting it at all. he is still being handsomely rewarded for playing, and its you and me (and others) who ae paying his wages. Lets not lose sight of that either.
