Club chairman Ben Robinson had previously claimed that he would be keen on bringing eight-time Olympic gold medallist to the club following his retirement from athletics.
Clough told Sky Sports: "I didn't know he [the chairman] picked the players, he'll have to come down and spend ten minutes in the technical area and see how he goes.
"Would that be a loan or permanent? I'm not quite sure. He would certainly add some pace. As long as he doesn't want much money I'm sure we will be OK."
