Fletcher joined his manager in believing the 10 changes, which admittedly did see Sir Alex Ferguson introduce eight full internationals, including Wayne Rooney and Rio Ferdinand, played no part in the result.
"There were not too many changes," said the Scotland skipper.
"We have a big squad and everyone has a lot of ability.
"It is difficult for the players coming in because they don't have that match sharpness.
"But training is intense and everyone is good enough to play in this team. The manager felt things needed freshening up and the team was good enough to win the match. I agree."
