Manchester United midfielder Owen Hargreaves believes he will be a better player once he returns from major knee surgery.
The former Bayern Munich star has already been told he will play no more football until next season after having operations on both knees to cure a long-standing tendinitis problem.
He told the Manchester Evening News: "I'm going to come back stronger and hopefully add a couple more years to my career.
"It's been frustrating at times.
"I don't really watch our games because, as an athlete, and being so competitive, it's hard to watch when you'd normally be out there."
