The Blues can go 10 points clear at the top of the league, putting them out of Tottenham’s reach before second-placed Spurs play sixth-placed Manchester United on Sunday (5.30pm).
While Chelsea are “buzzing”, central defender Gary Cahill warns against complacency.
He says: “It’s one more to go, we have two home games and one away so we’re in a very good position now.
“If anything we should be enjoying it. After the Tottenham result (against West Ham), naturally spirits were high in training and everybody was buzzing.”
Cahill said that Chelsea are keeping their concentration during the final push and are hopeful of getting a win at the Hawthorns, where they have won just once in their last five league visits.
“The pressure is still on because we have to win one game out of the three, but with the way we’re playing there’s no reason why we shouldn’t be confident. We’re still doing the right things, there’s no complacency.
“It’s going to be a tough game at West Brom, it always is. It’s never comfortable and we need to be aware of that, but we’re looking forward to getting the job done.”
