North London: Per Mertesacker
North West: Daniel Agger
It's a battle of the defensive rocks in our other showdown; both Mertesacker and Agger are classic defenders who won't budge an inch when confronted with a challenge.
Mertesacker was mocked for his lack of speed when he first arrived in England but has established himself as a mainstay of the Arsenal back four, while Agger has been at the heart of Liverpool's defence for some time.
It's a north London defensive partnership - Per Mertesacker just beats off competition from Agger. Liverpool have been a bit shaky at the back this term while Arsenal and Mertesacker have been more consistent.
