Two goals from Britt Assombalonga and one from Chris Cohen helped Forest to a 3-0 victory which preserved their Sky Bet Championship status, and Warburton has vowed never to let the club get in this position again.
He said: “We didn’t start the game particularly well in the first 30 or 35 minutes, then you hear about the results away from here and the crowd went a bit quiet. But we showed a lot of character, we deserved the win and the victory and I am delighted for the players and the fans; their support today was outstanding.
“The save from Jordan Smith was magnificent, a world-class save from him then we get the penalty that Britt put away with aplomb and then we go in at half time at 1-0 and it is in our control. We know what we have to do and we had to be positive.
“The worst thing we could have done was go on the back foot but we were positive, got the goals, missed the penalty but still got the third goal and there was great character shown by the boys and we got there in the end.
“The vow is we must never allow Forest to be in this situation again; it can’t happen. The last five or six weeks, the relegation dog fight, is not what we are about. Remember the feeling and the relief we feel now and that must not happen again.
“I have confidence that it won’t happen again and that comes from the quality of the squad. When we came in there was 33 or 34 players and that needs trimming but I have seen the quality of the experienced professionals and the quality of the young ones coming through.”
Warburton praised the effort put in by his side to secure the result needed and said that they rose to the occasion, led from the front by Assombalonga.
He said: “After that first half-an-hour, we started moving the ball and creating chances. Eric had a great chance and we didn’t maximise it but it showed what we could do if we moved the ball and the boys calmed down a little bit. It was a huge occasion, whether you are an experienced or young pro and they will be better off after today, I’m sure.
“Britt started the game slowly, then he came to life. He has power and pace and he comes to life in the box. It was a tremendous display from him and he could have had three or four. He took the penalty again and struck it well but he finished strongly. What he needs now is a good pre-season, that is the one thing he, and other players, has lacked to get the work in the bank and build from there.”
