Emmanuel Adebayor, F, Tottenham
One year ago, he was on loan at Real Madrid. This year, he's still on loan, but at Tottenham he's been on of the key differences between a Europa-bound side and a fringe title contender. Adebayor leads Tottenham in goals (10) and assists (10).
Mikel Arteta, M, Arsenal
A deadline acquisition from Everton in summer, Arteta has responded to his new surrounding by putting up the best passing numbers in England. Leading the circuit in both competed passes and percentage, Arteta will be asked to as prolific and accurate on Sunday.
Younes Kaboul, D, Tottenham
The 2011-12 season has been a breakout campaign for Kaboul, who has nailed down a consistent place in Spurs' starting XI. One of the best athletes in the league, his physicality will give Robin van Persie problems.
Laurent Koscielny, D, Arsenal
In a season-and-a-half, Koscileny has gone from obscure acquisition from the French league (not an uncommon occurrence at Arsenal) to the pleasant surprise, giving fans hope a pairing of Koscielny and Thomas Vermaelen can be viable. On Sunday, they'll have to prove so against Emmanuel Adebayor.
Scott Parker, M, Tottenham
An England international, Parker will be tasked with destroying Arsenal's build up, though he's no mere ball-winner. Parker's box-to-box tendencies make him on of the league's best all-around midfielders.
Wojciech Szczesny, G, Arsenal
Arsenal's young Polish shot-stopper is sure to be tested on Sunday, as just as he's done with the numerous tests he's faced throughout the season, he's likely to pass. Like Koscielny, Szczesny has been a pleasant surprise for Arsenal this season - somebody they can count on into the future.
Gareth Bale, LW, Tottenham
Perhaps the most dangerous player in the English league, Bale showed last year that Spurs need not control this fixture to have a chance to win it. Sunday will provide the young Welshman another chance to show he's the best left winger in the world.
Alex Song, M, Arsenal
Having established himself as one of the best defensive midfielders in England, Song will be tested on Sunday, having to protect his defense from the likes of van der Vaart, Modric, Parker and, when they cut in, Bale and Lennon. It's a big ask, but Song is capable.
Luka Modric, M, Tottenham
Gareth Bale is Spurs' most dynamic player, but he's not their most important, Modric will run the show on Sunday. Controlling play from the league's best midfield, a good day from Modric will lead Spurs to more derby success.
Robin van Persie
England's leading goal scorer, it's likely van Persie will have to find the net in order for Arsenal to get a result on Sunday. While van Persie has 22 goals this seaosn, no other Arsenal player has scored more than four.
