Inter Milan midfielder Patrick Vieira says he's partly to blame for his injury-plagued season.

"This season has been frustrating," he said to Sport 365. "I had a long-term injury that kept me out for four months and so the hunger to play really built up inside me.

"I made a mistake when I played four games in two weeks and I immediately injured myself elsewhere.

"Now I have more time to train and to work on my condition, I feel better. I need to play as much as I can so that I feel better."
