David Bell's hopes of a dream debut were wrecked as Norwich City crashed to another home defeat, but he insisted: “We will learn from our mistakes.”

The 24-year-old summer signing from Luton finally made his first appearance for the Canaries as a second-half substitute against Derby, who cashed in on keeper David Marshall's error to take all three points with a late winner.

Bell, playing for the first time since May after suffering an ankle injury in pre-season training with the Hatters, was sent on in place of Omar Koroma with nearly half an hour to go and was pleased with his contribution - but his day was ruined by the result.

He said: “At 1-0 down, we scored the penalty to get back to 1-1 and a man's been sent off and I thought, for 10 to 15 minutes after that, we picked up our momentum and started getting right on top. I thought then there was only going to be one team to go on and win it. The lads are very disappointed that Derby have managed to win the game, but we've got to bounce back from that and just look forward rather than look behind us. It takes the wind out of your sails but we can't sit and dwell on it too much.

“We have to learn from the mistakes, go into the break, regroup and kick on for the Bristol City game. It's not a good start but we've got to try to put it right and I'm sure we will.”

Manager Glenn Roeder, looking for crumbs of comfort as his team slipped to 21st place in the Championship after 10 games, said of Bell: “I'm very pleased. When you lose, you always look for positives and I thought David Bell, left side or right side, proved that he will be a good player for us. He's talented on the ball, knows what he's doing when he's receiving the ball, is a good footballer and he crosses a very decent ball as well, as we saw on a few occasions.”

Bell added: “I haven't played a lot of football in the last four months, so I'm delighted to get a run out on the pitch. I think now I just need to get some games under my belt to get match fit. I had a great reception from the fans and I appreciate that. I think they will be frustrated but I hope now I can get my foot in the door and they can see a lot more of me.”

After a spell on each flank during his brief appearance, he said: “I don't mind either, really, left or right - I'm not really that fussed as long as I'm playing.

“I don't need extra training. I just need some game time, really, minutes on the pitch. I'm hoping I can get as many games under my belt as quickly as possible.

“I've played here a couple of times for Luton - it's a lovely stadium, a lovely pitch and I'm looking forward to playing on it a lot more.”
