Odemwimgie also urged West Brom to keep up the level of performance shown in the second half for the rest of the season.
"At half-time the manager said the opposition showed more desire, and that touched every player in the dressing room," BBC Sport quotes Odemwingie as saying. "You could see the zeal which we had in the second half - it was two different teams.
"I am very happy for us. Give it five more minutes and we would have got the winner.
"If we play like we did in the second half we can be back to where we were at the start of the season."
West Brom are currently eighth in the Premier League.
