United suffered a stunning 2-1 loss at the Swiss Champions.

"Of course we're disappointed, there's no other way you can feel," said Ferguson.

"It's part of football. You have to deal with the disappointment, and this club has used it as motivation many times.

"These young players will feel disappointed tonight but they'll have to cope with it and go on with their careers.

"Our results in the last few years have been outstanding. It's a loss because it's the best tournament in the world. It's a marvellous tournament."
