Leeds manager Simon Grayson conceded his side did not even push Manchester United close in their 3-0 Carling Cup defeat at Elland Road.
Grayson fielded a full-strength side, while Sir Alex Ferguson made wholesale changes as two goals from Michael Owen and another from Ryan Giggs in first-half stoppage time saw the visitors romp into the last 16.
Grayson said: "You have to give credit to Manchester United. They caused us a lot of problems. We gave the ball away too cheaply. Too many individuals over indulged themselves rather than keeping it simple."
He continued: "When you do that against top players, they will punish you and we didn't do ourselves justice. Manchester United have the strongest squad they have had for years. The whole group played with immense confidence.
"The team they put out could have beaten a host of Premier League sides. It shows the gulf that is between us.
"I made a decision not to make too many changes because I wanted to give Manchester United a game. We didn't do that."
