Spurs held by battling Hammers
Tottenham lost further ground in the race for fourth place as they were held to a frustrating goalless draw in the London derby against West Ham at White Hart Lane.
Just 24 hours after being paired with Real Madrid in the Champions League quarter-finals, Spurs' chances of qualifying for next year's competition took a big blow despite dominating for large parts of the match.
Michael Dawson, Gareth Bale and Aaron Lennon all rattled the woodwork and Jermain Defoe was guilty of missing several good opportunities to break the deadlock, but Tottenham could not score, meaning they now trail Chelsea by two points while West Ham moved out of the relegation zone.
Three minutes had elapsed when Dawson picked up a Luka Modric pass and hit the bar with a superb curling effort.
West Ham continued to struggle as Modric and Rafael Van der Vaart both went close before Demba Ba slid Carlton Cole through against the run of play, but the former Chelsea man's weak shot was easily gathered by Heurelho Gomes.
With five minutes of the first half left, Lennon struck a post after racing down the right but the rebound off the woodwork caught Defoe by surprise and the striker's improvised six-yard effort went two yards wide.
Robert Green kept the scores level with a quick reaction save with his legs from Defoe's six-yard stab after Redknapp chose to switch Bale and Lennon.
West Ham performed much better in the second half, with Ba unleashing a 25-yard piledriver that Gomes saved magnificently with a diving one-handed save.
Pavlyuchenko fluffed a chance to put Tottenham ahead, but then almost immediately made up for his failure, drawing a top save from Green with a 25-yard drive.
Upson hacked down Modric on the edge of the box with six minutes left, handing the hosts a good opportunity to snatch the win. Bale stepped up and bent a left-foot shot destined for the top corner that Green somehow tipped onto the bar.
