Branislav Ivanovic gave the Blues the lead on the stroke of half time, but just as it seemed Jose Mourinho's men would close out the game and earn a valuable three points, Victor Anichebe rescued a point for Pepe Mel's side, and it was a well deserved point at that.
Chelsea stay top of the league, but wins for Arsenal and Manchester City tomorrow night would see Mourinho's men slip to third, as the title race continues to hot up.
Blues fans were understandably disappointed on Twitter after the game, and a number of players - and Mourinho himself - came in for strong criticism as Chelsea threw away their lead to gain just a point when it could, and probably should have been three.
Here are some of the reactions from Chelsea fans after the full time whistle.
Jose must be disappointed in the team tonight. Missed opp 2 go 4 points clear West Brom played very well tonight and deserve the point #CFC— Loren G (@LBVanderbilt) February 11, 2014
Opportunity missed tonight, we're still in the race, keep the faith boys #CFC— Evan Park (@Parkymarbella) February 11, 2014
After what he's done for the club I don't want to criticise Ramires but he's been awful for some while now. Effort there, quality ain't #CFC— The Special John (@bainesyDiego10) February 11, 2014
it's matches like these that Chelsea need to grind out victories if they want to become champions and today they failed to capitalize. #CFC— Nabae Asfar (@asfarfaketeams) February 11, 2014
Did anyone notice Oscar hasn't been in form since Mata was sold. Is he feeling like he doesn't have anyone to contend with or what? #CFC— IG: tunnyking (@Tunnyking) February 11, 2014
Shocking result. Best centre half injured. and worst of all players fighting amongst each other. What has happened? #CFC— chelsea fc (@talk_CFC) February 11, 2014
