Eden Hazard and Diego Costa provided the goals for the Blues, while Manuel Lanzini's strike came too late.
Entering Week 28 of the campaign, Chelsea can afford to lose three of their last 11 matches and still win the title if they win out the rest of the way―the Blues have only lost three matches all season long.
Here's a look at the current standings:
|Premier League Standings|
|8||West Bromwich Albion||27||11||7||9||36||34||+2||40|
The fixture list for Week 28:
|Manchester City||vs.||Stoke City|
|Bournemouth||vs.||West Ham United|
Hazard was the main star on Monday night at the London Stadium, scoring the first goal and guiding the Blues' attacking flow throughout the night.
The Belgian was set up by Pedro for the opener, with N'Golo Kante making an interception in midfield and launching a quick counter. Hazard and Pedro cleverly worked the ball between them, and the Belgian calmly finished the chance.
As shared by Rob Harris of the Associated Press, security at West Ham's ground wasn't paying attention in the aftermath:
Costa doubled the lead in the second half, converting from close range after a corner kick fell into the box.
Per WhoScored.com, the Spaniard has done a superb job of spreading out his goals:
Lanzini pulled one back for the Hammers late in the contest, but a comeback never seemed likely.
With the top four clubs in the league all winning in Week 27, Arsenal are the big losers following their loss to Liverpool at Anfield. The Gunners dropped out of the top four as a result and sit just one point ahead of Manchester United, who drew with Bournemouth.
Week 28 will be something of a mixed bag, as several top clubs will not feature due to the FA Cup. North London rivals Tottenham Hotspur and Arsenal are inactive in the league, and the same goes for Chelsea and United, who will face each other.
That match will undoubtedly soak up the headlines, with Jose Mourinho returning to Stamford Bridge, where he managed the Blues for years.
