Owen Hargreaves says his Manchester United debut at Eastlands was the "biggest moment" in his career.
"To play for Manchester United, in front of these fans, and to be around these players and coaches is fantastic.
"It was a great game to make my debut in. Naturally, I am disappointed we did not win but I am sure there will be a lot more wins in the future."
On the defeat to City, Hargreaves added: "We are creating enough chances but, obviously, we need to score.
"It is something we will have to work on in the coming games because really, by the time Manchester City scored yesterday, we should have been in front.
"The frustrating thing is that we have played well in all three games so far this season. But the key thing in football is to win and we need to start doing that."
