Nottingham Forest head coach Philippe Montanier was left to rue his side's wastefulness in front of goal following the 1-0 defeat at Brentford.
Scott Hogan's goal condemned Forest to a second straight loss in West London and Montanier believes his team had ample opportunity to find an equaliser and go on to win the contest.
Speaking after the game he said: "It was a frustrating evening for us. We had control of many parts of the game but it was the same story for us. We had many opportunities but lacking efficiency in front of goal.
"We hoped Britt could score in the final minute when he went through to celebrate the birth of his daughter but we had so many other chances tonight. That is the thing that is difficult to take.
"There were many positive parts of our play tonight. We managed to restrict Brentford to only a few opportunities in front of goal and we worked hard all over the pitch to create chances for ourselves."
Montanier was pleased by the majority of his side's performance at Griffin Park and says they will continue to make improvements to their game ahead of Saturday's clash with Wigan Athletic at The City Ground.
He said: "The mentality of the players is very good and we are working very hard to get that next victory. It is a difficult moment for us but it is a good moment to show the character in the squad and show how we can bounce back.
"Stephen Henderson had a very good night and he was very unfortunate to concede the goal. What we need to do now is take the positive parts of our game and combine them ready for the next game."
