Scottish giants Rangers are also interested in Martin, who is waiting for news about the club's takeover before making a decision. The club is looking for a new long-term manager after the departure of Philippe Clement. Barry Ferguson has been acting as caretaker, but it's unlikely he'll be offered the job permanently.

Leicester City, on the other hand, are expecting Ruud van Nistelrooy to leave the club. With the team facing a possible return to the Championship next season, a change in management is likely.
