London :Premier League leader Chelsea drew 3-3 with visiting Everton on Saturday for a fourth straight match without a win.
Didier Drogba scored twice as Chelsea recovered from an early own-goal by goalkeeper Petr Cech, but Everton fought back to equalize twice and secure a valuable point in its efforts to move away from the bottom of the standings.
Chelsea had not conceded a goal at Stamford Bridge since the opening day of the season in August.
It has now lost its perfect home record and could be joined on 37 points by Manchester United if the defending champion beats Aston Villa later on Saturday.
Manchester City equalized three times to hold Bolton 3-3 and draw for the eighth time in nine Premier League games, while Tottenham's hopes of staying in contention for Champions League qualification took a big hit with a 1-0 loss against visiting Wolverhampton Wanderers.
Spurs could lose fourth place to Villa and slip as low as sixth if Liverpool beats Arsenal in Sunday's only game.
Tottenham had 83 minutes plus injury time to recover from a third-minute goal by Wolves striker Kevin Doyle but missed several chances and lost a third home game of the season.
Birmingham moved to within three points of Spurs with midfielder Lee Bowyer scoring for a 1-0 win over former club West Ham, Fulham drew 1-1 at Burnley and last-place Portsmouth equalized in the final minute for a 1-1 draw at Sunderland.
But Portsmouth's Younes Kaboul got a second yellow card for removing his shirt in celebration of his goal and was sent off.
In the other games, Blackburn drew 0-0 with Hull and Manuel Figueroa scored from halfway to help Wigan to a 2-2 draw at Stoke.
