Nottingham Forest head coach Philippe Montanier was disappointed with how his side 'lost control' of the game during this afternoon's 2-1 home defeat to Norwich City.
The Reds had taken a first-half lead through Apostolos Vellios but Norwich produced a strong performance after the interval to take all three points and leave Montanier frustrated at his side's display in the second half.
He said: "We're disappointed because it's our first home defeat and also because we were leading at half-time. Norwich are one of the best teams in the league but we have to be more consistent over the 90 minutes.
"In the first half we had a good control of the game but that went away in the second half. We made too many mistakes with the ball and once again we've conceded two goals which is not good enough, especially at home.
"Norwich had eight shots on target today and we had two so that is not acceptable. That has been the difference today because we have not done well enough at either end of the pitch. They're a good side but we left it too late."
Vladimir Stojkovic made an excellent penalty save from Wes Hoolahan in the first half but Montanier wasn't impressed with how much his goalkeeper was tested this afternoon and admitted he may look to make changes ahead of Tuesday night's EFL Cup tie with Arsenal.
He said: "Vladimir has played very well but of course it is no good when our goalkeeper is having to play well to keep us in the game. We have to protect him better and we have to be stronger in defence to stop the ball getting to him.
"We have four matches in ten days so we have to try and keep the players as fresh as possible. But we aren't worrying about the Arsenal game right now, we have to focus and learn from what went wrong this afternoon."
