Tony Pulis was left particularly frustrated with Wednesday’s second-half showing in the defeat at Forest on Tuesday evening.
After watching the side make it eight games without a win since he took charge, Pulis said: “The goal at the beginning was really, really poor and it gave them a bit of a start.
“I thought we recovered from it and controlled big periods of that first half. We never created enough from the possession we had but we looked in control.
“I thought the second half was a different game. We didn’t come out with any zip, we then made a few changes but the changes didn’t actually help us.
“For the second goal, the challenge on Tom Lees was an absolute disgrace. The referee has not only missed a challenge that should be a red card but they also actually score their second goal from it. It was an appalling decision for me.”
With regard to the second half, when we failed to create an effort either on or off target, the manager said he thought we looked tired and added: “I felt our important players didn’t affect the game as much.”
On the overall performance he said: “I think the players are giving everything, the problem is it’s not good enough to win games in the Championship.”
Looking further ahead to the challenge of trying to keep Wednesday in the division and with the January transfer window approaching, Pulis said: “We need to improve the group of players. I have given a real honest assessment.
“There will be no sugar-coating. I have been in the game a long time. I have seen what it takes to get clubs out of this situation.”
