Frank Lampard finally earns his first home Premier League win as Chelsea manager

Giving further encouragement to Lampard, the Blues kept a clean-sheet for the first time in 10 games in all competitions this term.

Brighton have now lost all nine league meetings with Chelsea, setting a new Football League record for most games played against one opponent with a 100 percent losing record.

Graham Potter's team are winless in six league matches and sit just above the relegation zone.

Chelsea were without N'Golo Kante after he complained of a hamstring niggle following training on Friday, but the France midfielder wasn't missed in this one-sided encounter.

Tammy Abraham had scored seven goals this season and the Chelsea striker quickly forced Brighton keeper Mat Ryan into action after the ball broke to him following Mason Mount's failed penalty appeal.

Abraham's clever movement made him a constant threat in the early stages, especially when it was linked with Mount's passing.

Chelsea's dynamic young duo combined again as Abraham hit the far post with a glancing header from Mount's inswinging free-kick.

Despite their bright start, Chelsea would have been behind against the run of play if Kepa Arrizabalaga hadn't alertly raced off his line to save Neal Maupay's shot on the edge of the area.

- Killer second goal -

That escape came moments after Chelsea left-back Marcos Alonso had got away with only a booking after catching Martin Montoya with his elbow.

It was the reprieved Alonso who laid on a golden opportunity for Chelsea to take the lead when his teasing cross reached Ross Barkley at the far-post, only for Ryan to make a superb save to keep out the midfielder's close-range volley.

Chelsea finished the half by spurning two more gilt-edged chances.

Jorginho's pin-point lofted pass picked out Pedro's run, but the Spaniard shot straight at Ryan, then Alonso shot woefully wide from Cesar Azpilicueta's cross.

Lampard's men had 17 shots and 61 percent of the possession in the first half.

They needed just five minutes to make their pressure pay off after half-time thanks to Brighton's suicidal over-playing in defence.

Adam Webster was the guilty party with a miscued back-pass inside his own area that Mount seized on, provoking a clear foul by the panicked Albion defender.

Barkley had missed from the spot in Chelsea's recent Champions League defeat against Valencia and it was no surprise that Jorginho resumed penalty duties, the Italy midfielder slotting home his first league goal of the season with ease.

Ryan saved well from Pedro and Abraham as Chelsea chased the killer second goal.

Winger Callum Hudson-Odoi, back from a ruptured Achilles, came on for his first league appearance since April.

Brighton were inches away from equalising when Dan Burn flicked a header against the post.

But Willian wrapped up the points in the 76th minute when he burst onto Hudson-Odoi's pass and drilled a powerful effort that deflected off Burn's foot and beat Ryan at his near post.
