Nottingham Forest manager Aitor Karanka was left to rue missed opportunities in the first half of this afternoon's 2-1 defeat to Norwich City.
The Reds missed a number of chances after Lewis Grabban's early opener and they were made to pay as Timm Klose's brace handed the visitors all three points to leave Karanka frustrated.
Speaking after the game he said: "It was a difficult and disappointing day. We started the game really well, we scored the goal and hit the crossbar but sadly then we went down. We started to lose our intensity and Norwich played really well for the remainder of the game.
"I said to the players at half-time that we had to go for the second goal because we couldn't just sit and defend for the whole second half. We couldn't rediscover that intensity in the second half and we ended the game in a really disorganised fashion.
"More games like this will arrive during the season so we have to learn how to kill them off during the first half. When we play as we did in the first 20 minutes, we will always cause teams problems but we cannot just drop our intensity levels."
A season-high crowd of 29,427 were inside The City Ground and Karanka has urged the Forest faithful to stay on the players' side ahead of Wednesday's trip to Bolton Wanderers.
He said: "I understand that our crowd are demanding but we need to keep creating an atmosphere where they feel the support. I could see at times today that the players were feeling the pressure but we must understand the need to stay calm.
"It is fantastic to have 29,000 people inside the stadium but those bad moments are when the players need that support. It is not a critcism of the fans but sometimes we just need that bit of extra support from them at home."
