The Gunners have released a statement after the refusal of the Skipper Laurent Koscielny to involve in the pre-season tour.
Arsenal's preparations for the new season have been thrown into disarray after Laurent Koscielny, the club captain, refused to travel to the United States for their pre-season tour.
Koscielny is in the final year of his contract at the Emirates and it's understood he wants to leave the club this summer.
An official statement on the club's website read: "We are very disappointed by Laurent's actions, which are against our clear instructions".
