Sheffield United boss Kevin Blackwell apologised to the club's fans after the Blades were thrashed 6-0 by a youthful Arsenal side in the third round of the Carling Cup.
Blackwell named an experienced line-up for the trip to the Emirates Stadium, but the Championship outfit were blown out of the water by the youngest ever side in Arsenal's history.
"Sometimes you just have to hold your hands up and admit that you have been beaten by a better team," he told the club's official website.
"We have to move forward in the right way. If we learn from this experience it won't be too bad a night, but if we don't learn then we are in trouble.
"We had a great set of fans down here and I'd like to apologise to them if they feel we have let them down.
"We know we have to improve, but I can't afford to get carried away.
"We have a great set of lads and I love working with them, so let's see how they respond against Watford on Saturday."
