"I have full range of movement. It is a little stiff when I wake up in the mornings but when the physios do a bit of work on it and I do some swimming, it frees right up."
Looking further ahead to next Wednesday in Russia, he added: "We have lost out [in this competition] in the past against Liverpool and Monaco and I really don't want to sit back and say we have thrown it away again. We have the chance of a lifetime - a great squad of players and in great form at the moment.
"Man United have been in good form themselves but we are at the top of our game, we have everyone fit, and we need to take the game to them."
