All you need to know about Sunday's Premier League action

Leading with a huge result in the north London derby, football writer Tom Hancock looks at the key talking points from Sunday's Premier League action.

Eberechi Eze and Viktor Gyokeres both bagged braces as Arsenal thrashed local rivals Tottenham Hotspur 4-1 for the second time this season, restoring their five-point lead at the Premier League summit and condemning Igor Tudor to defeat in his first game as Spurs boss.

The teams went in level after a frantic first half which was paused for five minutes due to a problem with the match officials’ communication equipment.

Eze – who hadn’t scored since hitting an historic hat-trick in November’s victory over Spurs by the same scoreline at Emirates Stadium – sent the travelling Arsenal fans into raptures on 32 minutes. A determined Bukayo Saka sent a dangerous low ball across goal, which Eze controlled before coolly finishing on the volley.

The Gunners’ joy was short-lived, however: two minutes later, Declan Rice’s careless loss of possession on the edge of his own box let Randal Kolo Muani in to equalise by slotting the ball past goalkeeper David Raya.

That, though, was one of just six shots Spurs managed all afternoon as Arsenal well and truly dominated proceedings at the Tottenham Hotspur Stadium.

Mikel Arteta's men restored their advantage shortly before the hour mark – Gyokeres notching perhaps his most important goal for the club yet, receiving Jurrien Timber’s pass and curling one in from 18 yards – before Eze made it 3-1 soon after, intercepting Radu Dragusin's header to start a move which ended with him stroking the ball into an empty net.

Spurs came agonisingly close to setting up a grandstand finish but were denied by the brilliance of Raya, who showed no signs of any hangover from his costly mistake in Wednesday’s 2-2 draw at Wolverhampton Wanderers to somehow claw substitute Richarlison's attempt off the line.

Gyokeres then made absolutely sure of the points in stoppage time with his 10th Premier League goal, combining with Martin Odegaard before firing into the top corner.

By returning to winning ways after dropping points in each of their last two outings, Arsenal remain on course for their first Premier League title in 22 years. Spurs, meanwhile, are still languishing uncomfortably close to the relegation zone – they sit 16th, a mere four points above the bottom three with 11 games to go.

Both sides are in London derby action again next Sunday, with Spurs travelling to Fulham before Arsenal host Chelsea.

Alexis Mac Allister's strike deep into stoppage time made it back-to-back 1-0 away wins for Liverpool, who denied Vitor Pereira a valuable point in his first Premier League game in charge of Nottingham Forest.

The visitors seemed to have found some form with four victories from their last five games in all competitions, but they toiled during the first half at the City Ground, mustering only two shots to Forest’s 10.

Liverpool upped their threat in the second half, eventually going in for the kill during the closing stages.

Mac Allister thought he’d won it in the first minute of stoppage time when Ola Aina's clearance ricocheted off him and in – only for it to be ruled out for handball after a VAR check, the ball having struck the Argentina international on the elbow.

Forest might have snatched the points themselves soon after that, but Ibrahim Sangare fired just wide from distance.

But Mac Allister was not be denied with his next effort, in the seventh minute of stoppage time when he slammed the ball home after goalkeeper Stefan Ortega had parried Virgil van Dijk’s initial header.

A check for offside made things nervy for Liverpool momentarily, but the goal stood and Arne Slot’s men have now won three on the spin in all competitions without conceding. They stay sixth, but are now level on points with fourth-placed Chelsea and fifth-placed Manchester United, before the visit of West Ham United on Saturday.

Forest must take great encouragement from a performance which put the reigning champions on the ropes on numerous occasions, but they remain 17th, just two points above the relegation zone ahead of next Sunday’s trip to Brighton & Hove Albion.

Raul Jimenez bagged a brace as Fulham inflicted a second successive home defeat on Sunderland, who had been unbeaten at the Stadium of Light in the Premier League this season until narrowly losing to Liverpool earlier this month.

After a first half lacking in chances, the visitors broke the deadlock nine minutes after the break, an unmarked Jimenez putting them in front with a thumping header from Alex Iwobi’s corner.

It got even better for Fulham just seven minutes later, Jimenez converting from the penalty spot after referee Craig Pawson had been sent to the pitchside monitor to review Brian Brobbey's shirt-pull on Calvin Bassey.

Jimenez has now scored 13 penalties out of 13 in his Premier League career, giving the Mexico international the best 100 per cent record in the competition's history.

Sunderland were handed a lifeline with just under 15 minutes remaining when they won a spot-kick of their own as Ryan Sessegnon brought down Dan Ballard. Black Cats midfielder Enzo Le Fee scored from 12 yards to halve the deficit.

Any hopes of a home comeback were extinguished on 85 minutes, though, when Iwobi added to his earlier assist by latching onto Harry Wilson’s threaded pass into the box on the counter-attack and dinking the ball over Sunderland goalkeeper Robin Roefs for 3-1.

Victory moves Fulham into the top half and might just rekindle their European push following three straight Premier League defeats; Sunderland drop to 12th having now lost three matches on the spin themselves.

Fulham are back in action with a home London derby against Spurs next Sunday, while Sunderland travel to AFC Bournemouth for the Saturday lunchtime kick-off.

Crystal Palace finally ended a 10-match home winless run by edging past 10-man Wolves for their first victory at Selhurst Park since early November, thanks to substitute Evann Guessand’s 90th-minute goal.

Wolves had the ideal chance to take the lead when Mateus Mane was brought down in the box by Adam Wharton, only for Dean Henderson to save Tolu Arokadare's penalty.

It went from bad to worse for Wolves around the hour mark when Ladislav Krejci was booked for a foul on Ismaila Sarr and then, barely three minutes later, received a second yellow for kicking the ball away.

Palace left it late to make their one-man advantage count, but sub Guessand came up with the goods: the Aston Villa loanee met Tyrick Mitchell’s low cross to poke the ball past Jose Sa from close range.

Having squandered a 2-0 lead to lose 3-2 at home to Burnley last week, these will be a very welcome three points for Palace, who might just have been looking over their shoulder at the sides in the relegation scrap. Oliver Glasner’s side travel to Man Utd next Sunday.

Defeat for bottom club Wolves leaves them 17 points adrift of safety and still needing one more point to equal Derby County’s record-low Premier League total of 11.

They will hope to pick up at least that when they entertain local rivals Villa on Friday night.
