The victory, manager Harry Redknapp's fourth consecutive success at Upton Park, lifted Tottenham away from the drop zone and saw them replace West Ham into a safer 15th place in the Premier League table.

West Ham have won just once in their last 10 league games in contrast with their London rivals' revival under Redknapp.

Tottenham had to wait until 68 minutes into the game when defender King met Aaron Lennon's cross to open the scoring.

Gianfranco Zola's men almost grabbed a late equalizer but Heurelho Gomes made a fine double stop from Lucas Neill and David Di Michele.

From the subsequent break, substitute O'Hara found himself in space 20 yards from goal and he unleashed an unstoppable shot to seal the victory in the last minute.

Spurs could have scored earlier but Luka Modric fired straight at keeper Robert Green in opening minutes and striker Roman Pavlyuchenko hit the post just before half-time.

The hosts had the ball in the net on 22nd minute as a corner went in off Jermaine Jenas, but referee Chris Foy had already blown for a foul on the Spurs midfielder by Neill.
