Or David Wagner.
Other theories:
Or having seen the domestic cup final over, perhaps an approach for Enrique.
Or the fallout at Dortmund, or PSG.
Perhaps the last three are unlikely.
Or at the other end of the scale Exeter's L2 play off as we're waiting on Paul Tisdale.(again unlikely, but a theory none the less).
Going back to Stam though he probably hasn't done enough as in his end of season broadcast last season Les made a point of talking about managers experience at more than one club, and even country was mentioned.
