It's a shame for him that he has persistent injury problems, in his day he was a truly great player (despite playing for Liverpool) and he scored some of England's best ever goals against Argentina and Brazil. When he's fit, which is very rare, he is still a great player and hasn't lost his natural instinct for goal. His goals per game ratio at every club he's played for is one of the best around.
I was surprised United offered him a new contract in the summer, but I can't see him being there next year. Maybe it's time for him to accept his career is over due to his injuries and set up a poker school or become a horse racing tipster
