Couple of possibilites here. I think that the "foreign" man apparently interviewed on Sunday could still be Pat Fenlon. The Republic of Ireland is technically overseas and this could be a smokescreen by the club.
The other being could the club be waiting to see if George Burley gets the sack at Crystal Palace ? He would be a great appointment in my opinion. Would have the 'Well playing good attacking football, gives youth a chance and also would have good knowledge of the English lower league market, loans etc. As a bonus he has played for the club and would have a genuine feeling for the club. I think it would be the perfect fit for Motherwell and for Burley.
