Nottingham Forest defender Danny Fox believes The Reds should have been more positive and taken the game to Norwich City following yesterday's 2-1 defeat.
Apostolos Vellios' third goal of the season had put Forest in front but Norwich turned the game on its head through strikes from Jonny Howson and Graham Dorrans, leaving Fox and his team-mates to rue a missed opportunity.
He said: "We're obviously disappointed after going 1-0 up. They had the penalty which big Vladimir saved but then I think we had the better of the chances in the first half. I think we massively deserved to go ahead before half-time.
"Then we came out second half, started reasonably well but gave away a sloppy goal from a set-piece. We seemed a bit timid after that, we were a bit too worried about if we were going to lose rather than going to get the win.
"Norwich are a good side to be fair and we'll need to take positives from this game before the Arsenal match on Tuesday night. But we need to learn to be a bit more positive and cut-throat when we're going forward."
The visitors enjoyed plenty of possession in the second half at The City Ground but Fox says the Forest squad can only concentrate on what they can do ahead of Tuesday night's EFL Cup third-round tie against The Gunners.
He said: "We knew that Norwich would like to dictate possession but it doesn't matter whether the opposition are odds-on to be promoted or relegated, we should always set our stall out to be positive especially at home.
"We've shown in the first three home games that we can be a force at The City Ground but we need to look at ourselves, learn from our mistakes and hope to cause an upset on Tuesday night and progress to the next round of the cup."
