Robbie Keane equalized for Liverpool in a 1-1 draw at Arsenal in the Premier League on Sunday, although the Reds failed to take advantage after Gunners striker Emmanuel Adebayor was sent off.

Robin van Persie fired Arsenal ahead in the 24th minute at Emirates Stadium when he collected the ball on his chest, turned past two defenders and scored with a powerful shot.

But Keane, who returned to Liverpool's team after some poor performances, replied in the 42nd when he ran on to meet a long through ball by Daniel Agger, outpaced the Arsenal defenders and drove the ball into the roof of the net.

Adebayor was sent off for his second yellow card in the 63rd minute. Liverpool, which had Sammy Lee in charge because Rafa Benitez was absent while he recovers from surgery to remove kidney stones, created few chances and wound up with 39 points from 18 games.

That means Chelsea, which has 37 points from 17 games, can take over the league lead by winning at Everton on Monday.

In Sunday's other games, last-place West Bromwich Albion beat Manchester City 2-1 and Newcastle edged Tottenham 2-1.

Roman Bednar headed the winner in the third minute of injury time for West Brom, leaving City in relegation trouble.

Luke Moore's first goal for West Brom earned the Baggies a 69th-minute lead at the Hawthorns. But City substitute Felipe Caicedo replied in the 86th with a deflected backheel that hit the inside of the post and went in off goalkeeper Scott Carson.

The game appeared headed for a draw neither side really wanted when Bednar was left unchallenged to head home a right-wing cross from Gianni Zuiverloon.

It was West Brom's first victory in 10 games but Tony Mowbray's team remains last with 15 points, one fewer than Blackburn, which beat Stoke 3-0 on Saturday.

City, the Premier League's richest club after a buyout by an investment company from Abu Dhabi, has had one victory in nine matches to slide to 18th place with 18 points.

City manager Mark Hughes, who took over in June but now is the bookmakers' favourite to be the next Premier League manager to lose his job, said he expected to be given funds to strengthen the squad in next month's January window.

"I'm sure that once we get the quality into the side that we need then the performances and the progress we want to make will start to happen." said Hughes, who was unable to field Robinho because of injury and left out Brazilian countrymen Elano and Jo.

"We get compromised somewhat with absentee players so, until we get a stronger squad, then it's going to be difficult in the short term."

Damien Duff scored a last-minute winner in Newcastle's 2-1 victory over Tottenham to move up three places to 12th.

Charles N'Zogbia gave the Magpies a 12th-minute lead, but Luka Modric levelled it in the 29th. Only minutes after entering the game, Duff swapped passes with Mark Viduka to score Newcastle's winner. The loss means that Spurs stay in 16th place.

In Saturday's other games, Aston Villa moved up to third with a 1-0 victory at West Ham, Sunderland won 4-1 at Hull, Bolton edged Portsmouth 2-1 and Fulham outplayed Middlesbrough 3-0.

Defending champion Manchester United was away in Japan winning the Club World Cup on Sunday by beating Liga de Quito of Ecuador 1-0.
