daredevil Roberto Martinez is a decent club manager. He turned out to be a very decent international manager too. In fact you will find that most good club managers will turn out well in international football. Hiddink, Nagelsmann, Del Bosque, Lippi just to name a few. It's the easier job afterall.
Thus the reverse is often not true as well. Managers who made their name in international football often sucked when they get a club job as they are not capable enough to deal with the intricacies of day to day.
