Nottingham Forest head coach felt his side deserved to lose against Arsenal but was left frustrated with the size of the scoreline at the Emirates Stadium.
The Reds were on the end of a 5-0 defeat to exit the Carabao Cup and Lamouchi felt that his side showed their Premier League opponents too much respect in the first half.
Speaking after the game, he said: “We deserved to lose but five is too much. In the first half, at one down we were always in the game. We started much better in the second half then the second and third goals went in and we gave up a little bit.
“I cannot complain about the players. In the first half we didn’t play like we know we can. We had a lot of respect for the opponent tonight. We are out of the competition but against a big club, top players and I am disappointed for the players because it is cruel and disappointed for the fans because there were a lot of them here tonight.
“I think we showed them too much respect in the first half, then the second half we started well for 15 to 20 minutes. Then I thought to put Grabban on but after the second goal it was not necessary and I decided to save him because we don’t have much choice.
“The last pass, the last choice was not right but we cannot forget that we played against Arsenal, a top team with top players.
“Now we need to think about the next one, it is a different competition in the league and we will think of that from tomorrow. We need to try to be positive and think about Friday night.”
