The Swiss had brief spells on loan at Yeovil and Northampton last season and also had a trial at German club MSV Duisburg this summer but he returned to the Rams on each occasion.
However, a move could be edging closer after he spent last week with Danish league leaders OB Odense and scored during a trial match.
"They are very interested in taking him in January so we are just trying to get a deal done if they want to do one," said Clough.
"If not, we will probably look to get him out on loan. If we can do it before the deadline, we will do. If not, in January."
