Olivier Giroud admitted he had to leave Arsenal for Chelsea after what boss asked him to do

Olivier Giroud swapped his London allegiances from Arsenal to Chelsea because of a dispute with Arsene Wenger. The former Emirates fan favourite jumped ship to Stamford Bridge in January 2018 in a move that might have been viewed as a betrayal at the time. Former France striker Giroud, 40, spent five-and-a-half years with the Gunners and won three FA Cup crowns during that time. He returns to his former stomping ground on Tuesday when Lille visit north London in the Champions League group phase.
