Mason Mount put Chelsea back on track with the late strike that sealed a vital 1-0 win at 10-man Fulham, while Sam Allardyce got his first victory as West Bromwich Albion boss in a 3-2 success at Wolves on Saturday.
Chelsea boss Frank Lampard was under pressure after three Premier League games without a win and four defeats in their previous six matches.
The Blues were given a boost when Fulham defender Antonee Robinson was sent off just before half-time for a rash challenge of Cesar Azpilicueta.
Lampard’s men laboured to make their numerical advantage count, but England midfielder Mount finally broke the deadlock in the 78th minute when he drilled home from 20 yards.
That was enough to seal Chelsea’s first league victory since they beat West Ham just before Christmas.
Chelsea climb to seventh place, three points behind fourth-placed Leicester, who host Southampton later on Saturday.
Fulham remain in the relegation zone after their first defeat in six league games.
Former England manager Allardyce was able to celebrate after a pulsating Black Country derby at Molineux.
Allardyce had failed to win any of his first five matches since replacing the sacked Slaven Bilic.
Matheus Pereira shot Albion ahead from the spot before goals from Fabio Silva and Willy Boly put Wolves in the driving seat at half-time.
Semi Ajayi equalised after the interval and Pereira’s second penalty sealed West Brom’s first win in eight league games.
Albion remain second bottom of the table after their second league victory, but are just three points from safety.
“I thought the way the lads carried out their tactics was excellent. It’s the best I have seen us in possession since I have been here,” Allardyce said.
“The lads were excellent in the second half, their heads could have gone down with the results we have had recently but they came bouncing back.”
Wolves are winless in six league games and have not beaten the Baggies in 10 years.
It was the first time these two local rivals had met since 2012 when West Brom won 5-1 at Molineux and this was an equally memorable success for the visitors
