The veteran midfielder told manutd.com: "They've all done well and overall we're looking good. With all the loan players who have come back and the lads that we've signed, it's an exciting time.
"The players we've signed are talented. I've said before, though, that our main focus is defending as a team and not giving away too many goals. Because of the attacking options we've got we'll always create chances. If we can keep clean sheets, we've always got a chance - that showed last year."
Giggs also insists he doesn't feel pressure from the threat of Nani and Anderson to his first team.
"No, I don't think so. Over the last two or three years the manager has bought young players as he looks to the future, which is something you've got to do at this club. You can't stand still. Myself, Scholesy, Nev… we'll not play forever. We needed to bring the age of the team down and we've done that, but at the moment we've got a good mixture of experience and young players. Eventually these young players will be the future of United. The club never stands still and never will."
