Willian is on the verge of swapping West London for North London in a sensational switch.
The Brazilian, 31, will join a long-list of players to feature for both London clubs.
From Petr Cech and Ashley Cole to Nicolas Anelka and Olivier Giroud, those players could form a handy team of their own.
With that in mind, we’ve combined our best XI of players to have starred in both the red of Arsenal and blue of Chelsea…
PETR CECH
CECH spent over a decade at Chelsea between 2004 and 2015, winning four Premier League titles, the Champions League in 2011-12 as well as nine other trophies.
But he moved north to the Emirates – where he spent the final four years of his career – winning the FA Cup and two Community Shields.
LASSANA DIARRA
DIARRA joined Chelsea from Le Havre in 2005 – where he made just 13 Premier League appearances.
He joined Arsenal two years later, where he last just one season, playing seven times before moving to Portsmouth… and then, bizarrely, Real Madrid.
DAVID LUIZ
THE most-recent mover, Luiz was a surprise deadline day arrival for Arsenal in an £8m deal last summer.
The Brazilian spent six years at Stamford Bridge across two spells at the club – but left after being told he would not be an automatic starter.
WILLIAM GALLAS
ANOTHER to move straight from Chelsea to Arsenal, Gallas earned cult hero status at the Blues between 2001 and 2006 – having first joined before Roman Abramovich’s cash injection.
The Frenchman played 159 league games for the Blues and featured over 100 times for the Gunners too…
ASHLEY COLE
ARGUABLY the most controversial Arsenal to Chelsea mover, Cole spent a decade at Highbury having worked his way through their youth ranks.
After 159 games at Arsenal, Cole went on to have success at Chelsea, playing 229 Prem matches – winning one title, to go with his two from the Gunners.
DAVID ROCASTLE
THE Lewisham-born star spent ten years at Arsenal, having worked his way through their youth ranks.
After leaving, Rocastle played for Leeds and Manchester City, before heading to Chelsea where he spent a further four years towards the end of his career.
EMMANUEL PETIT
SPENDING three years apiece at the two clubs, either side of a season at Barcelona, Petit became a cult icon at both teams.
The 1998 World Cup winner won a Premier League crown with Arsenal – as well as an FA Cup and two Charity Shields – as it was then known.
CESC FABREGAS
SIMILARLY to Petit, Fabregas left Arsenal for Barcelona, before heading to Chelsea – much to Gooners’ annoyance.
Fab spent eight years at the Gunners, racking up over 200 league appearances, before returning to England three years later, where he spent five seasons at Chelsea, playing 138 Prem games.
YOSSI BENAYOUN
HARDLY a star at either team, having enjoyed his best years at Liverpool between 2007 and 2010 – Benayoun is still remembered by both clubs.
The winger made just 14 Premier League appearances in three years at Chelsea – with one of those seasons spent on loan at Arsenal, where he scored four times in 19 games.
NICOLAS ANELKA
HAVING played for so many clubs, it’s hardly a surprise Anelka played for both Arsenal and Chelsea.
The Gunners were the French talent’s first English club, where he scored 23 goals in 65 games, before moving to Chelsea over a decade later, scoring 38 times in 125 matches across four seasons.
OLIVIER GIROUD
ARSENAL fans were disappointed when Giroud left them after six years and 73 Premier League goals.
Now on the books of Chelsea, the striker has been rejuvenated after a slow start in West London.
