Liverpool swept to the top of the Premier League as Sadio Mane's double inspired a 6-1 rout of Watford, while Tottenham rescued a 1-1 draw at north London rivals Arsenal.

While Liverpool dazzled, their old rivals Manchester United ended a four-match winless run in the league as goals from Paul Pogba and Zlatan Ibrahimovic secured a much-needed 3-1 victory at Swansea yesterday.

Liverpool have emerged as genuine title contenders and Jurgen Klopp's side moved one point clear of second placed Chelsea thanks to a scintillating goal spree at Anfield.

The Reds took the lead in the 27th minute when Senegal winger Mane met Philippe Coutinho's corner with a header that looped past Watford goalkeeper Heurelho Gomes.

Just three minutes later, Roberto Firmino picked out Coutinho on the edge of the penalty area and the Liverpool forward fired home with a fine low strike.

Klopp's team were three up two minutes before half-time as Emre Can arrived unmarked at the far post to head in Adam Lallana's cross.

The goals kept coming and Firmino added the fourth in the 57th minute, the Brazilian finishing off Lallana's cross, before Mane got his second in the 60th minute with a clinical close-range effort from Firmino's pass.

Liverpool have won seven of their last eight league games and go into the international break with growing belief they can win the club's first English league title since 1990.

North London derby ends in 1-1

At the Emirates Stadium, Harry Kane marked his return from injury with the equaliser as Tottenham kept their hated neighbours from the Premier League summit.

Arsenal took the lead in the 42nd minute when Tottenham defender Kevin Wimmer headed a free-kick into his own net.

But England striker Kane, who had been sidelined for seven weeks due to ankle ligament damage, equalised for Tottenham from the penalty spot early in the 51st minute after a foul on Mousa Dembele by Laurent Koscielny.

Pogba's stunner ends Man United's wretched run

France midfielder Pogba put United ahead in the 15th minute with a sumptuous volley and Swedish striker Ibrahimovic bagged the second six minutes later with a shot that Swansea goalkeeper Lukasz Fabianski might feel he should have saved.

Ibrahimovic followed his first league goal since September with another one in the 33rd minute as he lashed in from Wayne Rooney's pass.

Swansea defender Mike van der Hoorn reduced the deficit in the 69th minute and there was late frustration for Ibrahimovic when he picked up a booking that rules him out of United's next match against Arsenal.

"I knew that Zlatan Ibrahimovic would score. It was always a question of time," Mourinho said.

"But one thing is a striker who does not score and does nothing for the team. He always does everything for the team."
