The very mention of the name 'West Ham' is enough to make Tottenham fans shiver, after they watched their team absolutely crumble against David Moyes' side at the Tottenham Hotspur Stadium in October.
Having been 3-0 up with just eight minutes of normal time to play, Spurs, well, they did a Spurs, and conceded three late goals to somehow only come away from the clash with a point.
The game was a microcosm of Spurs' season really, things started brightly but then they fell apart, and Sunday's trip to the Hammers offers the perfect opportunity to avenge their embarrassing draw.
Here's how Mourinho's side could line up for Sunday's London derby.
1. Goalkeeper & Defenders
Hugo Lloris (GK) - After starting the season strongly the Frenchman is struggling for form having shipped nine in his last three outings. Still, when Joe Hart is the alternative you can expect Lloris to keep his place.
Japhet Tanganga (RB) - With Serge Aurier sidelined through injury, Tanganga is again expected to fill in at right-back. The youngster couldn't have asked for a much tougher first Premier league appearance of the season than against Manchester City last week, and he'll be hoping for a more comfortable outing.
Toby Alderweireld (CB) - With Davinson Sanchez ruled out through a serious case of embarrassment following his Phil Jones-like attempt to stop Ilkay Gundogan last week, the veteran Belgian is expected to slot in alongside Eric Dier.
Eric Dier (CB) - Having been left out of the starting XI for a few of Spurs' recent league outings, Dier looks to have worked his way back into the manager's plans. A case of the lesser of two evils we imagine.
Ben Davies (LB) - With Sergio Reguilon ruled out through injury, the Welshman is likely to retain his place on the left-hand side of the Tottenham backline.
Pierre-Emile Hojbjerg (CM) - The combative midfielder was rested for Tottenham's midweek Europa League win over Wolfsberger, and he's expected to continue his record of having played every minute in the league for Spurs this season.
Moussa Sissoko (CM) - A big part of West Ham's success this campaign has been the impressive form of Tomas Soucek, and Sissoko could be key to Spurs' chances as they look to overpower the Hammers midfield.
Tanguy Ndombele (AM) - Who knows which Ndombele is going to turn up. The Frenchman is one of the most gifted and exciting players in the Premier League when he's on top form, but he just hasn't produced it consistently enough so far in his Spurs career. Still, he's exciting to watch.
Steven Bergwijn (RW) - Is the real Gareth Bale about to show us what he can do? Who knows, but after the Welshman's run out in midweek he's unlikely to be risked just three days later, meaning Bergwijn could be chosen to start on the right of the Spurs front three.
Harry Kane (ST) - The prolific frontman didn't feature in Spurs' Europa League tie on Thursday and so he should be fresh and ready to lead the line as Spurs look to avoid back-to-back Premier League defeats. Kane has 11 goals in 15 appearances against West Ham - only against Leicester (14) has he scored more.
Son Heung-Min (LW) - The rapid frontman grabbed himself a goal against Wolfsberger and was taken off midway through the contest. His linkup play with Kane will no doubt be vital if Spurs are to avenge their October collapse against the Hammers.
