Gonzalo Higuain scored his first Chelsea goals in a 5-0 rout of Huddersfield on Saturday, halting the slump after back-to-back English Premier League losses that created uncertainty about manager Maurizio Sarri's future.
In the striker's third game since joining on loan on Juventus, Higuain turned the ball into the net in the 16th minute and curled in Chelsea's fourth in the 69th.
"He has the quality," Chelsea teammate Eden Hazard said.
So often deployed as the "false nine" in the absence of the genuine thing, Hazard still scored twice. The first came from the penalty spot in first-half stoppage time, but he also netted from a tight angle in the 66th.
The victory against the league's bottom team was rounded off by David Luiz's header in the 86th.
Chelsea returned to fourth place ahead of Arsenal playing at defending champion Manchester City on Sunday.
EVERTON 1 - 3 WOLVES
A black cat strayed onto the field and stopped play for about three minutes at Goodison Park as stewards scrambled to usher it away.
Everton fans might have been glad of the respite.
They jeered loudly at the final whistle as their team lost at home to Wolverhampton Wanderers 3-1, a result that piled the pressure on Everton manager Marco Silva in what is increasingly becoming a miserable English Premier League campaign.
Goals by Ruben Neves — from the penalty spot — Raul Jimenez and Leander Dendoncker allowed Wolves to consolidate seventh place in an encouraging first season back in the top flight.
As for Everton, this loss came a week after an FA Cup exit at the hands of second-tier Millwall that ended any hopes of a first piece of silverware since 1995. The Merseyside club, which has spent $350 million on players in two years, is ninth in the league.
Andre Gomes provided the bright point for the hosts with a rising shot into the net that made it 1-1 in the 27th minute.
The cat wandered onto the playing surface midway through the second half and walked around at both ends of the field before finally leaving it as stewards gathered around.
Wolves manager Nuno Espirito Santo laughed on the sidelines, while Silva remained in animated discussion with his assistant.
BRIGHTON 0 - 0 WATFORD
Brighton's winless run stretched to five Premier League games as it was frustrated by an inspired performance from Watford goalkeeper Ben Foster in a 0-0 draw.
Former England international Foster twice kept out headers from Juergen Locadia and also saved from Shane Duffy and Florin Andone to earn his side a point at the Amex Stadium.
Javi Gracia's midtable visitors gave traveling fans little to cheer at the other end of the field but the draw was enough to push them above Everton into eighth position.
Brighton, which is seven points behind Watford, endured a frustrating afternoon with a result which extends its difficult start to 2019.
