Nottingham Forest head coach Sabri Lamouchi believes his side lost control of the game having taken an early lead against West Bromwich Albion at The City Ground.
The Baggies came from a goal down to beat Forest on the opening day of the season and although Lamouchi is taking positives from his side's start to the game, he was disappointed with the way they allowed Albion to hit back so soon after they'd hit the front.
Speaking after the game he said: "We started the game in a good way, the first 15 minutes were great but then we stopped playing and we allowed them to come back into the match. We've got to learn from our mistakes because we gave them two goals and of course it is very difficult to come back from that.
"I'm not saying anything against my players because they tried right until the end. We need to play with more personality and more experience and to learn from those mistakes. If you start the game well then you cannot give the opposition the chance to get back into the game just a few minutes later.
"The second goal can happen in football but the first one was very avoidable. Aro is a young goalkeeper who will learn from that mistake and he will help us a lot throughout the season. He knows that he needs to play with more courage and leadership in his penalty area.
"We must read the game much better. When you go 1-0 up early on you must create more space and encourage the opponent to come out of their shape and we didn't do that. We missed a lot of easy passes and that allowed them to come back into the game.
"Of course we know it is a bad start for us but I saw some positive signs in that performance. We need to go away and work on certain aspects of our game because we cannot just accept this result. The next game is even tougher away at Leeds so we must prepare well for that."
