He told the Sunday Mirror: "I think it's been one of my best seasons and it's just unfortunate that I've missed three months of it.
"Now that I'm back I feel very fresh and hungry. The game against Olympiacos was great and I want to carry that form on until the end of the season.
"I have a lot to offer. It was a bit of a rest for me even though you work very hard to get fit again.
"You come back hungry and strong and I think we have a few players like John Terry in the same boat."
