AC Milan coach Massimiliano Allegri has told Mario Balotelli that he is in danger of wasting his career.
The Manchester City striker was involved in a training ground bust-up with manager Roberto Mancini earlier this week, leading many to speculate that his future lies away from the Etihad Stadium.
It is the latest in a string of incidents to befall the Italian international since his £20m move from Inter Milan in 2010.
When asked if he could be tempted by a move for the 22-year-old, Allegri responded: "He is a Manchester City player. He just has to concentrate on himself, otherwise he can throw away his career."
Balotelli has scored one goal in 13 Premier League appearances this season.
