In the Premier League's equivalent of The Apprentice, Chelsea coach Jose Mourinho comes up against his prize pupil Andre Villas-Boas when his side visit AVB's Tottenham in the lunchtime kick-off at White Hart Lane.
Arsenal and Tottenham top the table, but Chelsea can move a point clear of their London rivals with a win in North London.
The two Portuguese coaches will be keen to put one over on each other having risen to the top of the European game together with their exploits at home and abroad - and especially as the two appear to have fallen out.
Here are a few things we think you should know about the best of friends, and enemies.
1. They earned their coaching badges in Scotland
Like Sir Alex Ferguson, both men earned the Scottish Football Association's coaching certificates. Bizarrely enough, AVB and Marcello Lippi were in Glasgow to help out with the draw for last year's Scottish Cup fifth round.
2. They are handsome dudes
Jose is one of the few coaches to be voted better looking than his players. Andre is more handsome than Juan Mata, who Jose is not playing at the moment.
3. They know how to get the best out of players
A sweltering of trophies illustrates their success. Jose also has a penchant for the European Cup.
4. They like longish coats
Not sure about the AVB Inspector Clouseau Mac, but The Rundown likes the look of Mourinho's long coat on a chilly day.
5. They love the UEFA Cup/Europa League
Jose said last week Chelsea do not have "Europa League players", but they might end up there after Crimbo. AVB always loves the Europa League having lifted it two years ago with Porto. Jose won it a decade ago.
6. They like socking it to Arsenal
AVB has a good relationship with Arsene Wenger while Jose and Arsene are now good mates, but nothing beats beating the Gunners.
7. They have been sacked by Chelsea
Mourinho received his marching orders in 2007 while AVB only lasted eight months or so at Stamford Bridge before being dismissed by the trigger-happy owner Roman Abramovich last year.
8. They are flexible in their movements having coached in various countries
Can't beat coaches and their silly poses. AVB looks particularly bendy below.
9. They have different attitudes towards John Terry
Not sure AVB and big JT saw eye to eye. Something that could never be said about Jose.
10. Neither have got the best out of Fernando Torres (yet)
Torres's agent blamed AVB for his struggles only weeks before he was sacked last year. Can't be too sure yet if Mourinho trusts Fernando to fire his side's title bid.
11. They look as windswept and interesting with stubble
Both like to go a few days without seeing a Mach 3. Like his doppelganger Juan Mata, AVB in particular goes for some facial fungus.
12. They amounted to little as footballers
Jose learned his trade helping translating for Bobby Robson at Sporting Lisbon and Barca, AVB learned his by helping Sir Bobby and Jose. See if you can pick out AVB in the below team photo from the early 90s.
13. They like life in the fast lane
They like their football first class. No second class travel for these fellows.
14. One of them will be looking like this if they lose on Saturday
The sinking feeling is never good especially to men with a touch of the theatre about them.
