Peterborough United boss Darren Ferguson is being linked with West Brom.
The Scottish giants are set to confirm Mowbray, 45, as their new manager early this week. The clubs just have to agree compensation with Albion demanding more than £1million.
Sir Alex Ferguson's son Darren, 37, is high on the list of potential replacements.
Ferguson jnr has won many admirers for guiding Peterborough from League Two to the Championship.
Alan Shearer is a rank outsider for the Albion job.
