The 34-year-old Frenchman has an agreement on personal terms with the Serie A giants until June 2023.
Giroud initially appeared to be on his way out after winning the Champions League with the Blues. But Chelsea's uncertain search in the market for a new number 9 compelled the Blues to confirm Giroud's extension until an offer came through.
Now that AC Milan is ready to finalize a deal, Stamford Bridge is ready to abide as the Blues try to nail down a sensational swoop for Erling Haaland.
Forever underrated, even mocked by national teammate Karim Benzema as a “go-kart” compared to the Madrid man's “Formula 1” quality, Giroud always shows up for club and country.
After all, his last goal for Chelsea was a bicycle kick against Atletico Madrid in the Champions League.
Giroud scored 39 goals in 119 appearances for the Blues and over a century of goals in six seasons for the Gunners.
