I'm living a dream I never want to wake up from.
I was saluted by Alex Ferguson when I was subbed and that made me very happy.
I am very happy to be signing for the best team in the world and especially proud to be the first Portuguese player to join United.
Lots of young players have triumphed at United, so why can't it happen to me? I'm not worried I'm young - it's an incentive to do the best I can.
