For two clubs with such rivalry over the past 20 years, Chelsea and Arsenal are familiar foes with many crossing the boarder of no mans land into enemy territory.
Chelsea have, more often than not, had the better of the deals. Whether it was signing Cesc Fabregas and winning two league titles with the Spaniard, having Ashley Cole in his primer years or watching Olivier Giroud win two European trophies in blue rather than red, Chelsea have had the better end of the stick.
Willian, David Luiz and Petr Cech all had better careers in west London before moving on as older players and ultimately failing to bring much to the Emirates Stadium. That doesn't count for much going into to the game on Sunday, but there is another way Chelsea can take advantage.
