When in doubt they should follow the example of David Coleman, who many decades ago found himself commentating on a game between Northern Ireland and the Soviet Union. The Soviet team included a Georgian defender who rejoiced in the name of Revaz Dzodzuashvili, and Coleman took care to refer to him throughout as 'the man marking George Best'.
I suppose we should be thankful that another man with a splendid name, Matevos Karapetovich Mkrtchyan, had too short a career as an international referee to come to the notice of British TV commentators.
