"Liverpool have strengthened with Fernando Torres and I believe Chelsea will be better again, so everyone at United will be on their toes. We're not resting on what we achieved.
"Last season I learned a lot from the likes of Ryan Giggs, Paul Scholes and Gary Neville about just what it takes to win the League, but players like them always look forwards rather than backwards and that's what people like myself have to do.
"But let's remember that we won the Premiership and that was a great achievement. We've strengthened the squad and things are looking good. But it won't just be the new signings that make a difference - the players who are already here will have improved as well."

"If you think about it too much, it can distract your focus from what the real job is.
"I always believe in myself playing with the players here and I always believed we could win the League last season.
"Whether people believed that at the start of the season or not didn't really matter to me, but I felt more like a United player the longer the season went on. It was a case of having a settling-in period, getting used to the way we play and the different expectations here. The challenge last season made me improve quite a bit, so, hopefully, I can keep doing that.
"You learn more from nights when it doesn't go so well, like Milan. I was away on holiday when the European Cup final was on and I didn't bother watching it because I knew it could have been us. That will drive the squad on this season to do better."
