LONDON (Agencies) - Chelsea's kept up its dismal run of results with a 1-0 defeat at last-place Wolverhampton on Wednesday night, one of the Blues' most embarrassing defeats in the Premier League. A fifth-minute own goal by Jose Bosingwa left defending champion Chelsea outside the Champions League qualifying places after two wins in its past nine matches. Bosingwa put Wolves ahead when he bundled a corner kick over his own goal line. Salomon Kalou missed a chance to equalize in the second half and Didier Drogba hit the crossbar. Manchester City fell two points behind Premier League leader Manchester United with a 0-0 tie at third-place Arsenal, with Robin van Persie, Cesc Fabregas and Theo Walcott hitting posts for the Gunners. City's Pablo Zabaleta and Arsenal's Bacary Sagna were ejected in the final minute after shoving each other. "The way we dominated the game is very positive," Arsenal manager Arsene Wenger said. "I feel we had more chances than you usually have in this type of game. They looked to me like they were set up not to lose. ... They came here to get a 0-0." Chelsea (10-6-5), the early season leader, has just 10 points from its last 11 games. Manager Carlo Ancelotti had said he was in danger of being fired following a 3-3 tie with Aston Villa last weekend. Manchester United (12-0-8) leads with 44 points, followed by Manchester City (12-4-6) with 42, Arsenal (12-5-4) with 40, Tottenham (10-5-6) with 36 and Chelsea with 35. Tottenham lost 2-1 at Everton, with American goalkeeper Tim Howard helping the Toffees to the win behind goals from Louis Saha and Seamus Coleman. Rafael van der Vaart had tied the score for Spurs. Howard had a pair of brilliant successive saves, the first of a point-blank shot by Van der Vaart, then palming over a long drive by Peter Crouch. Liverpool (7-9-4) is 12th following a 3-1 loss at Blackburn, with more chants from fans for manager Roy Hodgson to be fired. West Ham lost 5-0 at Newcastle, and Wigan rallied for a 1-1 draw at Bolton. Aston Villa slipped into the relegation zone with a 1-0 loss to visiting Sunderland. Ronnie Stam scored a late equalizer to salvage a 1-1 draw for Wigan at Bolton in the English Premier League on Wednesday after his goalkeeper Chris Kirkland was carried off with a head injury. Bolton went ahead in the 54th minute when striker Rodrigo Moreno, who was on loan from Benfica, beat Chris Kirkland from six meters (yards) after being picked out by Mark Davies. Stam levelled at the far post in the 80th, claiming his first Wigan goal by side footing home at the far post after meeting Steve Gohouri's cross. Kirkland was carried off on a stretcher shortly after the hour mark with a head injury following an accidental collision with Johan Elmander. "Chris is going to be in hospital for 24 hours as a precaution but the first report was very, very positive," Wigan manager Roberto Martinez said. While Wigan was still one point and a place above bottom-place West Ham, Bolton was seventh in the standings.
