It's always a biggie, but tonight Chelsea v Tottenham could mean the world (well, Europe) to either club. Here's how the Blues might secure a Champions League place.
Chelsea are defending far better in recent matches, with the midfield particularly playing its part to reduce openings. On Sunday Manchester United were actually prevented from scoring at home in the league for the first time since December 2009, a 0-1 defeat by Aston Villa.
Tottenham were unimpressive on Saturday when entertaining Southampton, who successfully stifled Spurs' pacemen and shackled the dangerous Gareth Bale until the last few moments.
As Saints left-back Luke Shaw discovered, it is one thing to know Bale is always going to push the ball onto his left foot and another preventing him from executing it. Either Cesar Azpilicueta or Branislav Ivanovic will have their work cut out at right-back.
The winner against Southampton was Spurs' only shot on target that wasn't blocked, and came when the wide man switched over to the right flank (something Ashley Cole must be alert to). He has scored in nine of his last 11 games - seven wins, two draws. The other two matches ended in defeat.
Unsurprisingly for an André Villas-Boas side, Spurs' play a high line of defence. It allows them to press the opponent in their own half and has caught opponents offside 112 times, topped only by Arsenal.
Yet it can also prove a crucial source of opportunity for the opposition: in the Europa League against Basel, for example, Mohamed Salah's goal and Jan Vertonghen's red card both derived from runs onto passes behind Spurs' advanced back line.
Should he feature, Frank Lampard is expert at finding gaps in a high defensive line with a first-touch through ball. Lampard, who has scored nine career goals against the Lilywhites, needs one to equal Bobby Tambling's all-time club record of 202.
Spurs play an open game but it sometimes extends to their own penalty area. Five of the goals they have conceded over the last seven matches were from corners, one each against Swansea, Basel home and away, Everton and Wigan.
Gary Cahill's thump from a corner also opened the scoring in our 4-2 triumph at White Hart Lane this season. The Yorkshireman will be eager to return to Chelsea's defence, as will another set-play threat, John Terry.
Bale missed that encounter as his partner was having a baby. Another absentee, Mousa Dembele, was taken off with a hamstring problem at the weekend, as was Aaron Lennon.
Squad fitnes news
Eden Hazard is available again having sat out the Man United win following a tight calf and but John Mikel Obi remains out with a hip injury and Ryan Bertrand joins him due a minor knee problem. Oriol Romeu is back training after his knee surgery in December.
Sandro, Younes Kaboul and William Gallas - scorer of a handball goal in the 4-2 game at the Lane - are not expected to figure for Spurs. Lennon and Dembele are expected to overcome their niggles.
