Borussia Monchengladbach boss Hans Meyer has aired his concerns regarding Steve Gohouri's attitude.
The Ivory Coast international faces an uncertain time in Germany, with his future the subject of much discussion of late.
The centre-half is believed to have attracted interest from the Premier League, with English clubs scratching around for bargains.
Gohouri has struggled to hold down a first-team place at Monchengladbach and recently withdrew himself from a friendly encounter citing a muscular injury.
"I did not have Filip Daems or Dante available for the friendly against Shakhtar Donetsk on Saturday, so it would have been a big chance for Steve Gohouri to stake a claim in the centre of our defence," Meyer told the Rheinische Post.
Gohouri has been sent for tests in an effort to determine the severity of his injury but Meyer is unsure as to whether the African ace has any physical problems.
"I will have to talk him," he added.
"Either he is actually suffering or he simply doesn't want to play for us."
Gohouri joined Monchengladbach from Young Boys Bern in January 2007 and has only 18 months left to run on his current contract.
He was reported to have been the subject of an approach from Wigan 12 months ago and could find himself falling under English eyes once again with Stoke and Sunderland both believed to be tracking his availability.
