I'd still play him ahead of the other options we have available to us. Give him a proper midfield to work with and he'll do a job.
It's gone beyond being an issue of service to him though, as his off the ball movement is dire. He is either finished completely, or disinterested.
Far from even considering giving him a new conyract, we should be looking to offload him now as even if he went for say 250k we would be saving over a million in wages.
I'd rather have McAleny starting, and I don't even rate McAleny. But at least he'd be running off the ball - with Saha you may as well play a traffic cone up front, same difference.
