LONDON: Arsenal remains four points behind leader Chelsea, giving
Manchester United, which is also on 11 points, the chance to take second place from the Gunners when it plays Bolton on Sunday.
Chris Brunt missed a first-half penalty for promoted West Bromwich, but Odemwingie fired the visitors ahead in the 50th minute at the Emirates Stadium after sliding in to meet JeromeThomas`s cross.
A gaffe by Arsenal goalkeeper Manuel Almunia gifted West Brom another two minutes later, when he knelt down to stop Jara`s shot but fumbled it into his own net.
Almunia was at fault again for West Brom`s third in the 73rd minute. He rushed out of goal, allowing Brunt to whip in a cross and Thomas, formerly of Arsenal, to score into the open net.
Samir Nasri almost single-handedly hauled Arsenal back into the game, as the France midfielder scored in the 75th and the first minute of stoppage time.
The match at Anfield started in bizarre circumstances, which led to Sunderland manager Steve Bruce accusing Liverpool of "unsporting" behavior.
Sunderland was awarded a free kick inside its own half and Turner gave the ball only a gentle knock in the direction of goalkeeper Mignolet, who was some 30 meters away.
"Everybody in the ground knew Turner was playing it back from where the free kick should have been taken," Bruce said.
But referee Stuart Attwell judged the ball to be live, and Liverpool`s Torres pounced on it before Kuyt collected the Spaniard`s pass to score.
Sunderland`s Darren Bent leveled 20 minutes later from the penalty spot and headed the visitors ahead in the 48th, but Liverpool captain Steven Gerrard nodded an equalizer in the 64th.
At Upton Park, Frederic Piquionne eased the pressure on manager Avram Grant by leaping high to power home Mark Noble`s corner to score his first league goal.
