It is a privilege to witness truly great sportspeople at the peak of their powers. It is often the case that an era might pitch two greats one against the other creating a jeopardy that is often tantalizing if slightly predictable.

In the opening decades of the 21st century tennis has delivered us a spectacle, infrequent in this or any other sport, which is the presence of 4 virtuosos at the height of their prowess competing for the major prizes.

Between them, Murray, Djokovic, Federer and Nadal were ranked in the worlds top 5 players for 15 years and achieved 66 grand slam titles. This created what will be remembered as the most demanding and competitive eras in modern tennis.
