Nottingham Forest boss Steve Cooper speaking to BBC Match of the Day: "I'm disappointed, really disappointed. Not even to draw the game but not to win it because it's a game we could have easily won but we haven't won it. We've lost the game on our own actions and when you think about that, you can't look past the goals which is an obvious things to say.
"We gifted them the first goal right at the start of the game through a lack of concentration and then the second goal we obviously do brilliantly to go 2-1 up and we concede a corner within three or four seconds of kick-off through not winning duels and concentration.
"We let people go and they equalise and then the third goal we have a throw-in more or less in the middle of the pitch and three or four seconds later there's another corner we have to defend and people don't make who they should and then there's a free header and a goal so for all the things that went on in the game, we can't look past our poor moments around the goals."
On whether lack of concentration was responsible for the goals conceded: "Desire definitely on the set-plays. Concentration of course and just a will at the moment in time to do better than what we did. It's a really pity because after gifting them a goal we then do well to come back into the game, 1-1, we should go 2-1 up at the start of the second half.
"Probably one of the best chances of the game, certainly from open play and then we do go 2-1 up after a brilliant team goal so to say we and I are frustrated is an understatement."
On Ward-Prowse's set-pieces: "Whether it's Southampton in the past or West Ham now, you play against James-Ward Prowse and you know it's going to be on the money.
"He's as good as there is and you know that coming into it but we haven't conceded goals through a lack of good planning or lack of strategy, we've lacked it in the end through desire to mark your man and not let him beat you and because we've not done that well enough it has cost us."
On reaching his 50th match as Nottingham Forest manager: "It means absolutely nothing at the moment."
