The Frenchman spent four trophy-less seasons in north London – in a deal that smooth Ashley Cole’s sour departure – and was handed the captain’s armband shortly upon his arrival.

Once his contract expired with Arsenal, he opted to seal a free transfer to fierce rivals Tottenham Hotspur – and remains the only player to have worn the shirt of the three London clubs.
