Everton twice came from behind to deny leaders Chelsea a home win at Stamford Bridge.
The Toffees went ahead after forcing an own goal from Petr Cech but found themselves behind in the 23rd minute following strikes from Didier Drogba and Nicolas Anelka.
However, Yakubu made it 2-2 at close range on the stroke of half-time. And, although Drogba volleyed home to restore Chelsea’s advantage, Louis Saha levelled the scores again with a header four minutes later.
Chelsea held onto top spot with 37 points, three ahead of second-placed Manchester United, while Everton moved to 17 points in 15th place, three points above the bottom three.
Frank Lampard came off the bench to convert a late penalty for Chelsea as they beat Manchester City 2-1.
Mario Balotelli gave Man City the lead after just two minutes, but Raul Meireles levelled before the interval and Lampard’s 82nd-minute penalty completed the turnaround.
The result left Chelsea third on 31 points, closing in on leaders Man City, who remained on 38 points.
