Olivier Giroud came off the bench in the second half to a rousing reception from Emirates.
Oli spent six years at Arsenal, scoring 105 goals in 253 games.
Although he was unable to stop Chelsea from being beaten 2-0 by the Gunners, it was his reaction after the match which caught everyone.
He paraded Emirates Stadium, applauding each side for all the love and respect he has received.
BELOW ARE SOME OF THE TOP REACTION FROM ARSENAL FANS ON TWITTER
Cheeky Giroud smile on the bench when Koscielny scored.
You can take Giroud out of Arsenal but you can’t take Arsenal out of Giroud.
Ha!

I’m sure I will be in the minority but always rated Giroud and miss having him as a plan B when needed class always shines through and this man always played for the badge on the shirt and never stirred things if not picked to start and gave 109% when he came on https://t.co/R825NAB60R
