Riyad Mahrez fired Manchester City back to the top of the Premier League as the champions won 1-0 against Bournemouth, while Hugo Lloris saved Tottenham in their draw with north London rivals Arsenal on Saturday.

Pep Guardiola’s side sit two points above Liverpool thanks to Mahrez’s second-half winner at Dean Court.

The only frustration for City in a hard-fought victory were injuries to Kevin De Bruyne and John Stones, which could significantly impact their bid to win an unprecedented quadruple.

De Bruyne hobbled off after the Belgian midfielder suffered a hamstring injury in the first half.

City, who are already without injured duo Fernandinho and Aymeric Laporte, also lost England defender Stones with a groin problem just after the interval.

But, showing the depth of City’s squad, it was Mahrez, who had come on for De Bruyne, who finally gave the champions the lead in the 55th minute.

Mahrez claimed his first league goal since December, the Algeria winger driving his shot under Bournemouth ‘keeper Artur Boruc.

“We made one of our best performances. People should understand how difficult it is to attack 11 players who are defending,” Guardiola said.

“We demand a lot of the players without giving them the time to rest physiologically, that is why it is incredible. No matter what happens this season they deserve my admiration.”

Liverpool can regain pole position if they win the Merseyside derby at Everton on Sunday.

Lloris rescues Spurs

At Wembley, Lloris saved a 90th-minute penalty as Tottenham salvaged a 1-1 draw in a pulsating derby.

Mauricio Pochettino’s side fell behind in the 16th minute when Aaron Ramsey slotted home from Alexandre Lacazette’s pass.

But Harry Kane won a controversial 74th-minute penalty to equalise for Tottenham.

Kane was offside when Christian Eriksen sent over a free-kick, but the flag stayed down and the England striker was bundled over by Shkodran Mustafi.

Kane calmly notched his 22nd goal of the season and his ninth in nine Premier League games against the Gunners.

Arsenal had a golden opportunity to take the points when Davinson Sanchez was penalised for a soft challenge on Pierre-Emerick Aubameyang.

Referee Anthony Taylor felt the minimal contact was enough to justify a penalty, but Lloris came to Tottenham’s rescue as the France star dived to his right to keep out Aubameyang’s low penalty.

Arsenal finished a bruising contest with 10 men after Uruguay midfielder Lucas Torreira was sent off for a studs-up foul on Danny Rose.

“VAR is coming to help them,” Arsenal manager Unai Emery grumbled when asked about Tottenham’s equaliser.

The dramatic finale ensured Pochettino, celebrating his 47th birthday, avoided a third successive defeat as Tottenham’s record run of 33 league games without a draw came to an end.

“Lloris’ save was a massive present. I am so happy because we didn’t deserve to lose the game – we were better than them,” Pochettino said.

Third-placed Tottenham remain four points ahead of Arsenal as the fight for Champions League qualification heats up.

United leapfrog Arsenal

Arsenal dropped to fifth place after Manchester United moved one point above them into fourth with a dramatic 3-2 win against struggling Southampton at Old Trafford.

Yan Valery smashed a fierce drive past United goalkeeper David De Gea for a memorable first goal of the young Southampton defender’s career in the 26th minute.

Ole Gunnar Solskjaer’s team equalised in the 53rd minute as Brazilian midfielder Andreas Pereira bagged his first Premier League goal with a long-range curler.

Romelu Lukaku, back in form after a long barren spell, put United in front six minutes later with a composed finish.

James Ward-Prowse drew fourth-bottom Southampton level with a superb 75th-minute free-kick.

However, in the 89th minute, Belgian forward Lukaku made it four goals in two games with the last-gasp winner.

Paul Pogba’s stoppage-time penalty was saved by Angus Gunn, but Solskjaer’s unbeaten domestic run as United boss has now reached 15 games.

“The belief is there, they have gone so long without losing games (domestically). The dressing room is bouncing at the moment. They were class finishes from Romelu,” Solskjaer said.

Elsewhere, Crystal Palace pushed Burnley back into relegation danger with a 3-1 win at Turf Moor, while West Ham beat Newcastle 2-0 with goals from Declan Rice and Mark Noble.

Wolves eased to a 2-0 victory over Cardiff at Molineux that left the visitors stuck in the relegation zone.

Brighton boosted their survival bid with a 1-0 victory over bottom-of-the-table Huddersfield at the Amex Stadium.
