Real Mallorca coach Llorenc Serra Ferrer has admitted that Alan Hutton's proposed move to the club has "become complicated".
The Scot, who spent last season on loan at the Spanish outfit from Aston Villa, had been expected to return to the club this summer.
However, Ferrer told reporters at a press conference: "I'm pessimistic. Everything had gone well, starting talks with Aston Villa.
"But it has become complicated because the player is now asking for other things and that cannot be. It has to stop."
A number of English clubs are reported to be monitoring proceedings.
