FINAL WHISTLE VERDICT: GOOD REACTION
There was little goalmouth action to speak of during the opening 45 minutes, but we appeared to have taken control of the contest when Samuel Eto'o broke the deadlock on the stroke of half-time, his third goal in the space of four days.
The match was turned on its head, however, when West Bromwich Albion scored twice in the space of seven minutes early in the second half, first through Shane Long and then soon after courtesy of Stephane Sessegnon, although the second goal was the source of much frustration for the Blues as Branislav Ivanovic appeared to have been fouled in the build-up.
With the clock ticking down, and the visitors set to inflict a first Premier League home defeat on Mourinho, Ramires was brought down inside the penalty area by Steven Reid; the referee pointed to the spot and Hazard stepped up to convert the kick.
As performances go, it wasn't a vintage one, but the Portuguese was pleased with the reaction of his players after going behind.
'I'm satisfied, the attitude in the first half was the correct one, be patient, wait for a mistake, wait for space. In the second half the first goal was our mistake, the second one was a referee mistake, which is part of football as well, and after that our reaction was either die or fight for life,' he said.
'We fought for life, threw everything into attack, it was no problem to take risks or lose 3-1 or 4-1 if they caught us on the counter-attack, which they had a couple of opportunities to do, so the attitude was good from a team that played in the Champions League on Wednesday and is playing in the Premier League on Saturday.'
On the performance
'In the first half, West Brom didn't cross the midfield line, we didn't create a lot because they defended very well, but the fact is we were the only team who tried to score and win in the first half. When the attitude to the game is this one, there is always one team who deserves to win more than the other.
'In the second half we had more space at 1-0, we had a couple of good situations, they scored a goal and then the second one was a big mistake by the referee, which even the fourth official told me was wrong. It was a big mistake.
'After that the reaction was fantastic, a reaction that could have ended with a 3-1, but we created a lot of chances, missed an open goal and threw everything at them. The penalty comes at a time when it's difficult for the team who are winning to accept because they were waiting for the final whistle and the penalty comes, but a penalty is a penalty, in the first minute or last, and this one was. In the game I didn't know, and from the bench I didn't know as it's too far, but from looking at the screen no doubt.
'They were very well organised, Steve (Clarke) is a good coach, defensively they are compact, well organised and committed, so they made it difficult for us.'
On the foul on Ivanovic in the build-up to West Brom's second goal
'It's a big free-kick, just in front of us, that's where I think the fourth official, instead of always looking to see if the manager is in the technical area or not, should participate in the game and it was right in front of him.'
On Hazard's composure from the penalty spot
'It was a big penalty, penalties in training sessions are easy to score, I can score them. Penalties if you are winning 3 or 4-0 are easy too. This was a difficult one and the kid was very calm.'
On the performance of Cesar Azpilicueta
'Azpilicueta is playing very well and played very well again. He played well against Schalke and again today, with zero mistakes. Of course, we were losing so I had to take risks. I preferred to play with three defenders, the powerful guys in the air that could also be a threat in attack, so I sacrificed Azpi, but he's played two very good games.'
On the impact in the title race of two dropped points
'To lose points at home becomes normal because no team has a clean record at home, to drop a couple of points at home in one match becomes normal for us and everybody else.
'Tomorrow there is a game when Arsenal can go seven points ahead of us if they win, or can drop to four ahead if other teams can win matches, especially the ones that fresh because they play on Sunday, but this is the Premier League.'
Clarke, meanwhile, was delighted with the performance of his side, particularly after the break.
'In the first half we frustrated Chelsea but didn't show enough ambition to go forward,' he said.
'We restricted Chelsea and in the second half we showed a lot more ambition. We needed the players to pass the ball better in the second half which is what they did.'
