This one was really, really interesting.
How many times have we seen teams drop back into a 4-4-1 shape after having a man sent off?
Two banks of four, seriously hard work for the lone striker and little to no creativity in the middle makes for a boring game for the neutrals, but Andre Villas-Boas had other ideas.
He went to three at the back by bringing Michael Dawson in, and dropped Gareth Bale and Aaron Lennon to the left- and right-wing-back positions respectively.
This gave Tottenham more attacking outlets than a 10-man team usually boasts, and it worked due to Bale's phenomenal drive, stamina and ability to link the play.
Spurs lost the match by three goals, but AVB didn't let the Gunners settle the match early and presented a constant threat to the scoreboard.
