Schalke general manager Horst Heldt has confirmed that he has spoken to Eintracht Frankfurt coach Armin Veh about a potential move to the club.
Veh, whose contract at Frankfurt expires in the summer, has been strongly linked with the post - held by Jens Keller until the end of the season.
Heldt worked with Veh at Stuttgart when the club lifted the 2007 Bundesliga title and said at the weekend: "I have a good friendship with Armin.
"I would be being unreliable if I was to say we have had no contact. I will not deny I have asked him what his general plans are.
"Jens Keller is and will be our coach until the end of the season. Then we will make a decision."
Veh said he would make up his mind about his next move soon, adding: "There will be a decision during the international break."
But Heldt said that if the coach opted not to extend his Frankfurt deal it would not automatically mean he was heading for Schalke.
"There is no deal, there are no negotiations, nothing of the sort," he explained. "Veh has his own mind and has worked for the freedom to choose what he wants to do and what he doesn't."
German media reports suggest that Veh is one of four leading candidates for the Schalke job alongside Keller, former Greuther Furth boss Mike Buskens and ex-Chelsea manager Robert Di Matteo.
