Turbo-charged London rivals Chelsea and Arsenal warmed up in style for their midweek League Cup showdown by turning on the goal power in the Premier League on Saturday.
Chelsea ended its recent struggles in front of goal with a 4-0 demolition of Brighton at the Amex Stadium. Hazard (2), Willian and Victor Moses were on target as the defending champion climbed to third in the standings with 50 points from 24 games.
Arsenal hosts its capital city rival in a League Cup semifinal second leg on Wednesday after the first game between the two clubs ended goalless earlier this month. Like Chelsea, Arsenal also turned on the goals Saturday, thrashing Crystal Palace 4-1 at The Emirates to remain in sixth place on 42 points.
Nacho Monreal, Alex Iwobi, Laurent Koscielny and Alexandre Lacazette put the game beyond Palace before Luka Milivojevic pulled one back for the visitors.
Second-placed Manchester United squeezed past Burnley 1-0 at Turf Moor with a 54th-minute goal from Anthony Martial while Paul Lambert celebrated his first game in charge of Stoke City with a 2-0 victory against Huddersfield, thanks to goals from Joe Allen and Mame Biram Diouf.
Jamie Vardy with a penalty and Riyad Mahrez struck as Leicester beat Watford 2-0, while Everton vs. West Bromwich Albion and West Ham vs. Bournemouth both ended in 1-1 draws.
Runaway leader Manchester City hosted Newcastle later Saturday. Fifth-placed Tottenham travels to Southampton on Sunday while Liverpool, which occupies fourth spot, visits bottom club Swansea on Monday.
