It certainly surprises me that Jose Mourinho is unbeaten against Arsene Wenger in nine meetings (five wins and four draws).
Arsenal have been a good side over the last decade.
Yes, they've never been as good as the "Invincibles" from the 2003-04 season, but you would expect Wenger to trump The Special One at least once.
Looking at the record, experts would be tempted to say that Mourinho has always had Arsenal figured out for Tuesday morning's (Singapore time) match.
But if you ask me, Wenger will finally get his first long-overdue win over the Portuguese.
Arsenal looked tired in their last three matches against Everton (1-1), Napoli (lost 2-0) and Manchester City (lost 6-3).
Fatigue is creeping into their side, which comes as little surprise considering how they've been on first gear since the start of the season.
The Gunners have not really had a game in which they could relax of late; not even in the Champions League.
But Arsenal have had a week-long rest for this London derby.
The Blues, on the other hand, had to endure a long, midweek journey to Sunderland, where they lost in the League Cup quarter-finals in extra-time.
I have to say I don't like the shape of this Chelsea side.
Their goalkeeper, Petr Cech, is not the same player as before, Gary Cahill isn't the best centre half at the moment, and even the ever-reliable Ramires hasn't been special this season.
