West Ham United and Manchester City kick-off the Emirates FA Cup third round with a mouth-watering all-Premier League tie at London Stadium.
The first-ever FA Cup match at England's newest football stadium is expected to be an affair featuring two strong starting XIs, with both managers Slaven Bilic and Pep Guardiola eager to make a mark in the world's oldest knockout competition.
A sell-out 57,000 crowd and millions-strong BBC One audience will enjoy another historic occasion for the Hammers and for Guardiola personally, who will take charge of his first FA Cup tie on Friday evening.
Here, whufc.com examines a trio of individual duels which could decide the game on the night.
Winston Reid has enjoyed a superb run of form at the heart of the West Ham United defence in recent weeks
The New Zealander leads by example - both figuratively and literally when Mark Noble missed Monday's defeat by Manchester United - and has made his presence felt at both ends of the pitch
Reid is particularly strong on the ground, where he is among the Premier League leaders in clearances made, while his anticipation means he is often in the right place to intercept through balls
At the other end, the No2 has contributed two goals and two assists, showing he has technical ability to go with his physical attributes.
Nicolas Otamendi is a more traditional centre-half, doing most of his work in the defensive third.
The Argentine has been more dominant in the air than Reid, while Pep Guardiola's style of play mean he also leads the Hammer in both passes made and pass-completion percentage.
These two English wingers are very different in terms of both their style of play and physique.
Michail Antonio is a direct straight-line runner who can knock the ball into space behind his marker and run onto it, using his acceleration, speed and strength.
He is also very strong in the air, often out-sizing his full-back and possessing an almost superhuman spring.
Raheem Sterling is a smaller, more elusive player who relies more on his technical ability and short, sharp movements to lose his man and create space. Sterling's statistics suggest he is a better passer than his West Ham counterpart.
Fans of outstanding playmaking ability and players who can make key passes through the tightest of windows are in for a treat tonight.
Two of the Premier League's very best creators will go head-to-head at London Stadium in Dimitri Payet and David Silva.
The Frenchman leads Europe's top five leagues in key passes made this season, while Spaniard Silva has been opening English top-flight defences up for years.
They are different players, though. Payet is a stronger player physically, able to collect the ball in tight situations and bounce his way through challenges with outstanding balance and technique with either foot.
Silva is smaller in stature, and more likely to play a quick one-two in tight areas, but he also possesses a tenacity that is perhaps understated.
Both, it goes without saying, are capable of scoring truly spectacular goals from any position.
