It could well be all or nothing for Chelsea.
Come Sunday evening, the Blues could be sitting eight points off the final UEFA Champions League qualifying place with just seven matches of the Premier League season remaining.
Defeat to fourth-placed Tottenham on Sunday will likely leave Antonio Conte’s side staring at a season without the Champions League football for just the second time in 15 years.
“If we win on Sunday we’ll go very close to Tottenham. Otherwise it will be difficult to take a place in the Champions League,” conceded Conte this week.
The good news for the Blues boss is that Chelsea are unbeaten in their last 27 home league matches against Spurs (W18 D9) since losing 2-1 in February 1990.
Indeed, Spurs’ 25 games at Stamford Bridge without winning in the Premier League is the most that one team has played on one ground without a single victory in the competition.
But this is a very different Spurs side to the one that we’ve seen for the bulk of the Premier League era – they’ve won more points in Premier League London derbies this season than any other side (13 – W4 D1 L2).
And the Blues are looking to do their first league double over Tottenham since the 2005-06 season.
But Tottenham will be without Harry Kane, which will have a major impact on their chances of all but cementing a top-four finish.
Under Mauricio Pochettino, Tottenham have won 59% of their Premier League games in which Harry Kane has featured (won 77/131) compared to just 39% when he’s played no part (5/13).
Instead, they will look to the in-form Son Heung-Min, whose Seasonal Pressure Index score of 74/100 proves he is a man for the big occasion.

After a run of nine games in all competitions without a goal, Son Heung-Min has scored seven in his last five for Tottenham.
The hosts, meanwhile, have had 51 different goalscorers against Tottenham in the Premier League (excluding own goals), more than any team has had against another in the competition.
And after a difficult second half to the season, Alvaro Morata will hope to become the 52nd at a time when his team need him most.
Who will handle the pressure?
