I'm not interested in keeping players at the club who don't put the effort in. All the talent in the world means nothing without the right attitude and approach.
Didn't he take a personal trainer with him on holiday over the summer though? It'd seem strange that he'd go to that sort of effort on his holiday (when he could have just lay in front of the beach for a week with his feet up), yet when it comes to his actual job/training he lacks effort?
