Laurent Koscielny has gone on strike after a bitter row over a new contract.
Koscielny, 33, is now facing disciplinary action and being stripped of the captaincy after refusing to fly with the rest of the Arsenal squad to the United States.
But Mirror Sport can reveal the background to the fall-out is that Koscielny has had a three year contract offer from Bordeaux and is also upset at what he sees as being made to take a pay cut by Arsenal.
France defender Koscielny has one year left on his current £120,000-a-week deal, wanted an extension and had held discussions with the club about getting an extra 12 months.
Arsenal were willing to give Koscielny a new two year deal but because of his injury record they offered a lower basic salary which included performance-related pay based on appearances and the option for a free transfer next summer.
