Olivier Giroud described his Arsenal career as a "beautiful story" after swapping the Gunners for Premier League rivals Chelsea.
France striker Giroud scored 73 Premier League goals during his five-and-a-half-year stay at Emirates Stadium, but has made just one top-flight start this term.
Giroud's chances of first-team football had further diminished after Arsenal forked out a club-record sum to sign Pierre-Emerick Aubameyang from Borussia Dortmund on Wednesday.
Chelsea's pursuit of a target man during the January transfer window eventually yielded results with the signing of Giroud, and the 31-year-old thanked the Gunners fans after completing his move.
I spent five and a half amazing years within the arsenal family. This beautiful story ends today. Thank you for your warm welcome. I would like to especially thank the fans for their unconditional support upon my arrival January 31, 2018
