The Gunners have been tracking the Morocco international frontman for some time, with the player admitting recently that he was heading to Emirates Stadium.
While the Gunners are delighted to be closing on a top target, Bordeaux have been left disappointed, and Club president Jean-Louis Triaud has revealed that the Ligue 1 outfit did everything in their power to keep the African ace at Stade Chaban Delmas, but accepts there is nothing more he can do.
"We have proposed extensions to Marouane. Our first proposal was on January 1, 2009," he said.
"I have had two difficult transfers since I arrived: Wiltord and Chamakh. These two departures relate to Arsenal.
"Had he accepted our proposal, he could have improved his contract.
"I think he was surrounded and badly misguided. I did not appreciate at all how it went. As president, I resent it."
Triaud, though, has no personal animosity towards Chamakh.
He added: "Personally, I owe him all my affection. He is a lovely boy. He is a warrior and a fighter. He has not cheated.
"I wish him success at Arsenal. I will see him again with pleasure.
"I have great affection and gratitude for him. He brought a lot of things at the club. But I still don't appreciate the way he left."
