The Under 23s were 3-0 up after 36 minutes through goals from Donovan Wilson, Aaron Collins and Sherwin Seedorf.
After pulling a goal back in first half stoppage time through Todd Cantwell, Norwich then went on to score in the 89th and then in the 4th minute of added time to secure a point for the visitors in the Premier League Cup.
A disappointed Scott Sellars said, “Ultimately if you’re 3-0 up and it sends up 3-3, then obviously you’re going to be disappointed.
“I’m disappointed for the lads, I thought we played some good stuff especially in the first half.
“We couldn’t sustain it and ultimately I don’t think we’re good enough at defending at the moment to keep clean sheets.
“We always look like we might struggle - we have to score lots of goals to win games and that’s not good enough for us.
“It’s something that we’ll keep working at but we ultimately question the deciton-making of some of our defending at times.
“The boys are certainly learning the hard way at the moment - we’re not picking up points, we’re not winning games that we deserved to win.
“I thought we were excellent first half - we could have been a goal up after 30 seconds but we ended up 3-0 up.
“We conceded a poor goal before half time - I said on the touchline that there would be a lot of goals in the game.
“I thought our front lads were better than their defence and I thought their front lads were better than our back four as well.”
Monday’s game saw the return of Ben Goodliffe and Sherwin Seedorf who have both spent time on the sidelines with injury.
Sellars felt that the turning point of the game came when Ben Goodliffe was forced to be substituted 18 minutes from time.
He said that his team lacked a natural desire to defend after that point, something that he says his side need to learn from.
“I felt that up until their second goal that we weren’t under any real pressure.
“I think taking Ben Goodliffe off had an effect on us - Ben’s just come back after having a long spell out through injury so we had to take him off because he was cramping up a little bit,” Sellars said.
“I felt as soon as he came off, we lost a little bit of physicality and aggression in defence and then I did feel in the last 15 minutes that Norwich looked like they might score.
"It’s about natural desire to defend and block and do the ugly things - I don’t think this is something we’re very good at at the moment.
“It’s something that these lads have got to recognise and do something about it.
“We’re not getting carved open, they’re not 45 passes through us, the last goal is a big boot over the top and we don’t deal with it - it’s poor.
“It’s still early in the cup, there’s only two games played and we’ve got four points.
“If you look at Bury away and Norwich at home - to pick up four points, you’d say that’s o-k.
“With the standards we set, we should have won that game.”
