Ruthless Manchester City returned to the top of the Premier League after hammering West Brom 5-0.
The in-form Ilkay Gundogan scored twice while Joao Cancelo - tipped at 11/1 by Tom Carnduff - Riyad Mahrez and Raheem Sterling also netted in the Hawthorns rout.
City moved above Manchester United, who can reclaim top spot by beating Sheffield United on Wednesday, after an 11th straight victory in all competitions.
It is their longest winning run for over three years and they sent an ominous message to their title rivals – moving seven points clear of Liverpool and making light work of Kevin De Bruyne’s injury-enforced absence.
In contrast, the Baggies have now lost their last five top-flight home games – their worst run at The Hawthorns in the Premier League in 17 years – while conceding 22 goals in the process.
Albion remain second bottom and six points from safety with Sam Allardyce yet to see his side score at home, having overseen a scoreline of 0-17 in those four matches.
Southampton 1-3 Arsenal: Gunners fight back at St Mary's
Arsenal came from behind for the first time in a Premier League game this season to beat Southampton and move to within five points of the top four.
The Gunners saw their defence of the FA Cup end with a fourth-round defeat at St Mary’s on Saturday but they returned three days later to record a 3-1 victory.
Southampton looked on course to see off the visitors once more as Stuart Armstrong fired them ahead with a fine third-minute volley.
But Arsenal would go in ahead at the break as Nicolas Pepe and Bukayo Saka struck, with Alexandre Lacazette making sure of the points.
The win moves Mikel Arteta’s side above Southampton and up to eighth in the table, just five points behind London rivals West Ham – who occupy fourth place after a win at Crystal Palace earlier in the evening.
Newcastle 1-2 Leeds: Pressure piles on Steve Bruce
Jack Harrison condemned Newcastle boss Steve Bruce to fresh misery as Leeds ended their three-game losing streak with victory in the Premier League match at Newcastle.
The midfielder clinched three points with a sweet 61st-minute strike four minutes after Miguel Almiron had cancelled out Raphinha’s first-half opener to leave the beleaguered Magpies head coach without a win in 11 games in all competitions and having taken only two points from the last 27.
Opposite number Marcelo Bielsa will have been delighted with another impressive attacking display, and equally pleased with the way they dug in in the face of a determined fightback which ultimately came up short, if only just.
Bruce had added attack-minded duo Ryan Fraser and Jacob Murphy to the mix in the search for inspiration, and although his team got better as the game progressed, they emerged without reward once again.
Crystal Palace 2-3 West Ham: Tomas Soucek leads comeback
A brace from Tomas Soucek helped West Ham come from behind to win 3-2 at Crystal Palace and move into the Premier League top four.
David Moyes watched his in-form side make a poor start to the London derby when Wilfried Zaha grabbed the opener after three minutes.
But it was largely one-way traffic afterwards, with Soucek hitting a first-half double to take his tally for the campaign to seven while Craig Dawson wrapped up the points with a fine header after the break.
The Hammers have now won their last six games in all competitions and are up to fourth which has put them in the mix for European football next term.
