West Bromwich Albion 0-4 Chelsea

Chelsea have won all 16 games where Eden Hazard has scored since Antonio Conte became the club's boss

Chelsea cruised to an easy away win over West Brom to increase the pressure on Baggies head coach Tony Pulis.

Alvaro Morata scored his eighth Premier League goal of the season when he converted a rebound after Albion goalkeeper Ben Foster had parried Eden Hazard's low shot.

Hazard made it 2-0 shortly after when he collected Morata's flick and took the ball around Foster, before Marcos Alonso volleyed in a third from Cesc Fabregas' free-kick.

In the second half, Hazard scored his second of the game with a curled finish from 18 yards out after another excellent Fabregas pass.

The victory was Chelsea's fourth successive league win, while West Brom remain without a win in all competitions since 22 August, a run of 11 games.

Chelsea move up to third, behind Manchester United, who beat Newcastle in the late game, and leaders Manchester City, who won at Leicester.

Tough times for Pulis

With Chinese club owner Guochuan Lai at a Hawthorns match for the first time in six weeks, Albion fans booed their side off at half-time and again at the end as their side's miserable season continued.

Albion won their first three matches in all competitions, but have not won since and this result leaves them 17th in the table, only one point and one place above West Ham.

Pulis, who has been the Albion boss since January 2015, was asked earlier this week if he would be surprised if he lost his job.

He replied: "No, not at all. If the club decide what they decide, I've got great respect for the football club, the supporters, the chairman, the board - it's just life. It's the way it is. If you don't get results, you're under pressure."

But his side were outplayed by the reigning champions, with Albion only producing two shots on target and never seriously testing away goalkeeper Thibaut Courtois. Substitute James McClean shot wide when through on goal late on for West Brom, who have only scored three times in their last five matches.

Pulis guided his side to 10th last season, their best finish in four years, but faces an uncertain future after another poor performance from his side.

Big challenges ahead for Chelsea

It was a perfect start for Chelsea in a big week for them.

On Wednesday, they visit Azerbaijan to play Qarabag in the Champions League, knowing a win will secure their place in the last 16. With Chelsea in command at The Hawthorns, Conte was even able to give Fabregas, Hazard and N'Golo Kante a rest in the second half.

The damage was done in the opening 40 minutes with a ruthless Chelsea performance. Foster will feel he should have done better with the first goal as he could only push Hazard's shot into Morata's path, before the Spanish striker created the second with a sublime backheel flick that enabled Hazard to round the goalkeeper.

Poor marking from Albion saw Alonso left unmarked to volley in a third from close range, before Hazard sealed the rout with a lovely finish for Chelsea's fourth.

The visitors, who are next in Premier League action next Saturday with an away game at fifth-placed Liverpool, could have won by a bigger margin, but Morata shot over.

Marcos Alonso's goal was his third of the season for Chelsea after scoring twice in a 2-1 win over Tottenham in august

'I don't think Pulis can survive this' - analysis

BBC Final Score pundits Garth Crooks and Martin Keown thought this could be Pulis's last match in charge of the Baggies.

Crooks said: "Tony Pulis looks a resigned figure on the touchline.

"At the moment, he does not seem to be able to offer anything to his team. The Baggies have been roundly beaten today, while Chelsea have played with a freedom and panache.

"Slaven Bilic cut such a forlorn figure towards the end of his time at West Ham, and that quickened his downfall. The same could be happening here to Pulis. The hatch on the trapdoor is opening.

"It would have been different if they had gone down fighting and lost only 1-0. But the Baggies owners were there watching today. Are they going to give supporters what they want, which would be a new manager?"

Tony Pulis took over West Brom in January 2015 and the club have finished 13th, 14th and 10th in the last three seasons

Keown added: "I don't think Tony Pulis can survive this. Partly that's down to the brand of football - we are coming towards the end of his time at The Hawthorns.

"This sort of poor West Brom performance is game after game. The Baggies need a shot of creativity right through the club. Are the players being asked to play football by the management?

"This has been a long time coming, and this result and performance today is really going to test the resolve of the owner."

Man of the match - Eden Hazard (Chelsea)

Eden Hazard has scored five goals in his past six games for Chelsea

Conte celebrates a Premier League landmark in style - stats

• West Brom have lost 17 of their 22 Premier League games against Chelsea, their highest total against an opponent.

• The Baggies have gone 10 league games without a win since mid-August and only earned 12 points from their past 21 fixtures (won two, drew six, lost 13).

• West Brom's only league victory in 10 home matches spanning eight months was on the opening day of this season against Bournemouth (drew three, lost six).

• This was Tony Pulis' joint heaviest home Premier League loss, matching his 4-0 defeats by Man City (October 2016) and Chelsea (January 2013, as Stoke boss).

• This was Antonio Conte's 50th Premier League game in charge of Chelsea. The reigning champions have earned an unrivalled 118 points under him since the start of last season.

• Chelsea have won 10 of their last 12 away games in the Premier League, losing twice.

Chelsea only had seven shots on target, but four of them ended up in the back of the net

'I'll keep ploughing along if they want me to' - reaction

West Brom boss Tony Pulis told BBC Sport: "Our defending for all of the goals was really poor. Against the top teams, you have to defend better than that.

"It leaves me in the position I was in before the game. The board of directors will decide what they have to do. I have been in this position before. It's up to them. I feel for the players. They have worked hard but they have made basic mistakes.

"I spoke to the owners yesterday; they are really decent people. It's not about them, it's about what's best for the football club. That is more important than anybody. It's a decision they have to make. I'll keep ploughing along if they want me to do."

Chelsea manager Antonio Conte told BBC Sport: "Tony Pulis is a really good manager with great experience. He was the manager of many teams and his team is very difficult to face, always.

"The game became easy but it wasn't. From the start of the season, there has been a lot of pressure on us, never mind Tony Pulis. Every team has pressure. They are a good team and they can find the right solution.

"Morata and Hazard have a great link. They are now 100% fit. It is easy to forget that we started the season without Hazard."
