Chelsea cruise to a 3-0 victory over 10-man Leeds United. Mount curled a lovely first-time effort into the top corner with just four minutes on the clock.
Things only got worse for Leeds as Dan James received a straight red card for a rash tackle on Kovacic 20 minutes later.
Chelsea upped the pressure after the break, with Pulisic drilling a low shot into the bottom corner to double the lead.
Lukaku then sealed the points late after keeping his cool to fire past Meslier.

MOUNT SCORES! Chelsea works it well from left to right, and Reece James has acres of space down the right. He wrongfoots Struijk before laying it off to Mount, and he hits the shot the first time. He wraps his foot around it, curling it past Meslier and into the top right corner. That is not the start Leeds wanted! 1-0 Chelsea.
PULISIC SCORES! Once again, it comes from Chelsea’s right as it’s worked infield, and Mount flicks it to Pulisic on the edge of the D. He takes it around Cooper to open up the space before drilling a low shot past Meslier into the bottom corner. 2-0 Chelsea.
LUKAKU SCORES! It didn’t look like he’d manage it for a moment, but he finally found the back of the net! Llorente lost the ball, and Loftus-Cheek finds Ziyech. He squares it to Lukaku, who keeps hold of it as Struijk slides in. Three Leeds defenders are clipping at his heels, but he keeps his cool and lifts his shot over Meslier. 3-0 Chelsea.
So, what’s next?
With that defeat, Leeds stays in the relegation zone, still level on points with Burnley, though they’ve now played one game more than the Clarets.
They’ve got two big games left, starting with Brighton and Hove Albion on Sunday.
Chelsea takes another step toward qualifying for Champions League football next season.
Their attention now turns to the FA Cup final against Liverpool on Saturday.
