Tottenham Hotspur travel to West Ham on Saturday looking to avenge two defeats by the Hammers earlier in the campaign.
Sam Allardyce's side have already won twice at White Hart Lane this season, winning 3-0 in the Premier League before triumphing 2-1 in the League Cup.
Spurs know they cannot afford to drop any points if they are to overhaul faultering Everton and secure a Europa League play-off round place.
The Toffees, who are fifth, are currently poised to enter the Europa League at the play-off stage but are just three points ahead of Spurs in sixth.
Sixth place will take Spurs into the third qualifying round of the tournament after Manchester City won the League Cup and then secured Champions League football for next term.
For West Ham, the aim is to secure their top-flight survival after a frustrating season which has seen them hovering just four places and five points above the relegation zone at this late stage.
With four consecutive defeats heading into the game, manager Sam Allardyce is under pressure at Upton Park. The number of supporters who would like to see an end to the former Blackburn Rovers boss' reign is increasing.
Spurs are without Andros Townsend, Kyle Walker and Erik Lamela, but Mousa Dembele, Etienne Capoue and Jan Vertonghen could return.
Allardyce has confirmed in his pre-match press briefing that only on-loan forward Marco Borriello is missing.
