LONDON — Fast-forward to next July and picture the scene with great rivals Novak Djokovic of Serbia and Britain's Andy Murray going toe-to-toe in a thrilling Davis Cup quarter-final.
It would be a magnificent occasion with the current world numbers one and two fueled by national pride and the decibel levels in the stands pumped up.
Whoever prevailed would probably then be lining up a mouth-watering clash with Roger Federer's Switzerland.
That scenario is unlikely to happen, however, because the packed ATP Tour and the Davis Cup schedule are often incompatible for the leading players and next year's Olympics in Rio de Janeiro will clutter their plans still further.
