Wolves boss Mick McCarthy admitted the 2-1 defeat by Birmingham was hammer-blow given their domination for much of the clash at St Andrew's.
Kevin Doyle's first-half lead had put McCarthy's men on course for a vital three points, until veteran striker Kevin Phillips came off the bench to score two goals in the last 10 minutes.
He said: "I have not been in our dressing room before and seen the lads as disappointed as that after a game.
"You feel hard done by, and it is hard, but we've got a game on Wednesday (against Tottenham) and that is the motivation we need.
"If we play like that in our remaining games, I don't think we can be written off.
"I had no doubt that the team would perform and they have done that on many occasions this season."
