Another big win for West Brom at home, and the Albion are now up to 14th in the Premier League, and more importantly they are now four points clear of the drop zone. How important that could prove to be.

Here are some key stats from tonight's game at Stamford Bridge:

• Chelsea are unbeaten in their last 20 Premier League home games against Everton (W11 D9 L0).

• Chelsea have won 34 of a possible 36 points (W11 D1) in their 12 home games this season.

• Everton have won one of their last nine Premier League games (W1 D3 L5).

• Chelsea have kept 16 clean sheets in their last 20 Premier League home games, conceding just six goals in that run.

• Everton have won just 27 points in 25 Premier League games this season - 18 points fewer than they had at this stage last season in Roberto Martinez's first campaign as manager at the club.

• No Chelsea player created more goalscoring chances (3) or attempted more crosses (10) against Everton than Juan Cuadrado (3).

Manchester United manager Louis van Gaal: "I didn't like this performance today. Of course, we have won and the result is fantastic. But after this match you cannot say that we are going up and I want to progress every match. Daley Blind has a headache and maybe tomorrow it is better. I don't think Blind will be out for next Monday's game. But for Phil Jones, I fear. I don't know. We'll have to wait and see tomorrow."

Here's more from Everton manager Roberto Martinez: "Football can be very cruel. I think it's very clear that the home team are trying to influence the referee. From that point on it's unfortunate. We constantly see it here. We have to allow the authorities to look into it.

"I think we've shown good signs in our recent performance. We've been really solid. What pleases me today is that we were very cute, frustrated Chelsea and created the best chances. That needs a good balance, especially at the hardest place in the Premier League.

"It's been a difficult season but we're looking forward to the final third of the campaign and European football. The performance was dynamic, full of confidence."

Chelsea manager Jose Mourinho: "Big game, big game. We found a different Everton, it's a compliment. A defensive Everton, very well organised and compact, very dangerous on the counter attack. They made it difficult for us.

"We tried everything and the spirit was amazing. The pressure was strong and they were in trouble for the last 10 minutes. We scored a goal which the linesman disallowed very well but everyone was inside their box for the last 10 or 15 minutes.

"In the end we got a very important goal.

"I don't have a view of the melee. In the first half Everton made lots of fouls, every attack was a foul. Gareth Barry could have been sent-off in the first half and Roberto Martinez at half-time replaced Muhamed Besic because he was afraid of the red card. At the end the emotion was high."

Everton boss Roberto Martinez told BBC Sport: "We were in control. We had clear-cut chances, the best ones of the game - they needed world-class saves from Petr Cech. It's a shame we couldn't convert the chances. It's a huge disappointment. Our performance deserved a positive result.

"Every time a player loses a challenge it feels like the weight of the world is on the referee's shoulders and he feels he needs to react. To give Gareth Barry a second yellow card because of the reaction from Chelsea's players is disappointing. They surrounded the referee and their conduct was a real shame. It created a little bit of belief for Chelsea and the goal came as a consequence of that. It was a very scrappy goal - if you don't have the momentum often they don't end up in the net."

Gareth: All the pessimism around Villa completely ignores the fact that a squad with class players like Benteke, Delph and Cole has quality in abundance and the next four games are eminently winnable. A smart managerial appointment to pep the squad up is all that's needed.

Dave: Some people are calling the Chelsea victory lucky. They had 21 shots versus only seven for Everton. Fully deserved the win!

Matt in Southampton: Mourinho delivering a title-winning performance tonight. Cagey 1-0 wins are what his champions are made of.

Burnley manager Sean Dyche: "It's a tough business we are in and this game can sometimes kick you in the rear. The manner, energy and organisation... it was all on show tonight. But we have to turn performances into wins. I thought Danny Ings was terrific. But I could say that about the whole team."

Manchester City manager Manuel Pellegrini, speaking to BBC Sport: "We returned to our normal performance, especially in the second half. We scored three goals in the second half and had more chances.

"It is important, not just the score, but also because it is not easy to score four goals at Stoke. They have been the difficult team for us to score against while I have been here. It is a tough place to come. The most important thing was to win and in the way we did today."

On Sergio Aguero's disallowed goal for handball: "Maybe he could not stop because he arrived running to the goal. It is difficult to understand."

Stoke City manager Mark Hughes: "I was more than pleased with what we produced in the first half, in the second half there were factors that meant we were not able to get at them. You leave yourself open when you are chasing as the home side and that is what happened.

"We have done really well in the last nine or 10 games. We did really well in the first 45 minutes but City were able to take it away with their bit of extra quality in the second half."

West Ham boss Sam Allardyce on 5 live: "That's more than a good point. We had to cope with going down to 10 men, which was a very difficult decision to stomach. Our keeper was fouled, no doubt about that. And then Andy Carroll got injured again, and just had to stand up front as nuisance value.

"The defending was absolutely magnificent and that point feels like a win. We've given our travelling fans a lot of heart with that spirit and the way we defended.

"It's the same injury as before with Carroll. He was declared fully fit the other day, but it wasn't a dangerous challenge on him. It was a knock and it's caused him the same injury again, which is obviously a concern for us. That's a big blow, and we have a thin squad at the moment."

Southampton manager Ronald Koeman: "If you play 30 minutes 11 against 10 then you have to score the goal but we didn't. Everybody was running and we didn't make the pitch wide to make the space. There were too many crosses and I think that is the easy way for them to defend.

"I think we had one or two shots from outside the box and lacked sharpness up front. I said at half-time if we kept the organisation, the front players have to win the game tonight but they didn't.

"You have to react and work harder and be sharp in the box. Maybe in one or two situations Graziano Pelle was a little bit unlucky but he was not on the level he can bring."

"Paul Lambert wasn't at his best with TV. All the radio and press reporters will say he was good with us. He'd josh with us, give us gossip, be frank. He liked an anecdote about his time in Scotland or Germany. He was really good company, totally different from what you saw on the television. He used to sit and talk to us for 10 minutes before we even started. We'd give him pelters in terms of questions, but I respect him for never taking it personally.

"That Villa squad is not a bad one, and if they go down I'd suggest that was one of the better squads to have been relegated from the Premier League. They just need a good coach on the tiller. They need to unpick that goalscoring lock.

"Lambert loved Villa, loved the club. He was steeped in the club's history from day one. In his last game at Norwich they beat Villa 2-1 at Carrow Road. The Villa fans were chanting for him, and there was universal respect and approval for his appointment in 2012."

West Ham manager Sam Allardyce on Andy Carroll's injury: "It was the same injury he has had before. He had a kick in the back of the knee and the injury has reappeared. He's done three days training and it obviously wasn't as good as we thought it was."

On the potential signing of Lassana Diarra signing: "That's not going to happen because of administration reasons, which is a real shame. Fifa regulations apparently, so after all the work we've done there and to get a player of his quality with a lot to prove would have been a huge bonus for us."

Everton have won just 27 points in 25 Premier League games this season - 18 points fewer than they had at this stage last season in Roberto Martinez's first campaign as manager at the club.

West Ham manager Sam Allardyce, talking about Adrian's sending-off: "It's a foul on the goalie. Sadio Mane had two hands around him. It's bizarre why they can't see it but this is what we have to stomach today and it nearly cost us dearly. It lost us the opportunity to win the game and we had to battle with nine in the end when Carroll got injured to get an unbelievable point.

"It shows the character and resilience to get a fantastic result. It's almost like a win and a fantastic performance. "

Chelsea goalkeeper Petr Cech told BT Sport: "This game was all about the first goal - and we got it. We had a few dangerous moments going forward. Everton played very well, they were brilliant the whole game and made it difficult for us. We had to wait for our chance to come and it came right at the end."

I've still not seen a definitive replay of the melee at the end of the game. Will Branislav Ivanovic be facing some disciplinary action?

Chelsea midfielder Nemanja Matic told BT Sport: "I think we did a great job. I would like to share my man of the match trophy with the other 25 players. We fought for each other for the 95 minutes. We won this game with our heart. This game showed that every game will be difficult, especially in this part of the season. We are a bit tired because of so many games. We will give 100%, we have to continue to play like we have been playing."

Chelsea manager Jose Mourinho: "It's beautiful to win in the last minute, and it's so sad to lose. They have to be very disappointed, they gave us a very difficult match. We are very very happy and we think we deserve it. We fought so hard to try and win the game.

"We risked a lot to try to win. It was a refereeing performance that in my opinion was very good. We had a goal which was fantastically well disallowed by the assistant referee. A great decision.

"Everton changed its DNA, they defend really well and made lots of fouls. What we can call intelligent fouls. But if the referee follows the rules it's yellow card, yellow card and they paid the price for that. This is not a criticism, but they foul, foul, foul.

"Did Branislav Ivanovic go in with his head? Don't make me laugh. Don't make me laugh."
