The 36-year-old was delighted with their performance in the 3-1 win on Sunday.
“I felt we controlled the game,” said Giggs. “Chelsea are a good team and at times we made them look ordinary.
“It is always nice to win in this manner and that is what we will take out of it.
“The aim of pre-season is to get through with no injuries but obviously you want to win games as well.
“We are confident and our pre-season has gone well and we topped it off with a good show.”
“If you look at the squad at Wembley, there were players who didn’t even get on the bench,” added Giggs.
“There’s Rafael, Federico Macheda, Wes Brown, Tom Cleverley, who has done brilliantly pre-season. There’s Rio Ferdinand, we have got Anderson to come back.
“We have got a really strong squad, so injuries permitting throughout the season, we can be stronger than last year.”
