Jose Mourinho was left frustated as his charges failed to capitaise on a 1-0 half-time lead to draw 1-1 with a last-gasp equaliser from WBA tonight.
"Maybe they deserved an equaliser as they were strong in the last 20 minutes," said Mourinho.
"I'm frustrated as we had chances to kill the game. We have had this in the past,
"In the last 20 minutes they put us under pressure and they scored a goal as a consequence. Maybe they deserved that point. A point is a point and at the end of the season we will see.
"I think the game for 60 minutes was completely in our hands, West Brom didn't put one foot in our box. We couldn't kill the game
"We were punished because we could not cope with the pressure they put on us and we did not finish the game off earlier.
"I was feeling it. I was feeling that we only thing we could do is defend well. We were not strong enough to get out in the last 10 minutes. The game doesn't end until the last whistle and the defensive mistake led to the goal."
