Giroud thoroughly enjoyed his two-year spell at Montpellier, and admits he owes the club for helping him move forward in his career.
"A lot of things went right for Montpellier last season. It was an incredible season for us and one that I will never forget," he said.
"I will always have great memories of my time at the Club and the people and the fans.
"I want to say thank you to Montpellier because they gave me the possibility to play in the first division in France, join Arsenal and come to the Premier League, and then play in the Champions League.
"But they know that I recognise and appreciate the opportunity that they gave me."
