However, Giggs feels that a loss of this type will help the inexperienced learn and believes it can be a positive for the club even though they are now out of the league cup.
"It's tough to take. When you score four goals away from home more often than not you win the game,” said the Welshman.
"I'm proud of the young players who played, though. There were some great performances. They will have learnt a lot and you learn more from losing as well.
"You try and take the positives from a game like that but there are a lot of disappointed lads and rightly so because they put in good performances.
"But they'll learn from it and the experience they'll gain from this is more than they could ever get from a reserve game.
"They had to stick all their big guns on in the end to make an impact which they did. As I said, though, I'm proud of the young players – they never stopped battling."
