An abiding personal memory of Louis van Gaal's time at Manchester United is of watching him telling Wayne Rooney how to take a penalty.
It was summer of 2014 and Van Gaal's side were training at Washington's FedEx Field ahead of a friendly against Inter Milan.
Van Gaal was the new manager and Rooney his new captain. But that did not stop the great Dutchman calling a halt to a penalty practice session to take hold of Rooney by the shoulders and walk him through exactly the technique he believed would work best.
