Swansea City have refused to work with Michael Laudrup's agent Bayram Tutumlu, which has thrown the manager's future into doubt.
Tutumlu has been Laudrup's agent since the Dane's playing days with Barcelona, but Swansea chairman Huw Jenkins has fallen out with him over a disagreement over transfers, reports the South Wales Evening Post.
The club finally refused to stop communicating with the agent after the two fell out over the potential sale of team captain Ashley Williams.
More than two weeks ago, it was reported how Laudrup had fallen out with the club's board over transfers and it seems as though the issue has still not been resolved.
Laudrup led the South Wales club to a Capital One Cup triumph and a ninth-placed finish in the Premier League, which has sparked rumours linking the manager with a move away from the club.
Jenkins's hard line may prompt Laudrup to seek a job elsewhere, with Fenerbache just one of a number of clubs said to be interested.
