Kings of Tennis

Tennis legends will participate during Kings of Tennis in Stockholm. John McEnroe, the American who has been called ''One of the most iconic athletes on the planet'', is set to play against Stefan Edberg and another six legendary superstars from the ATP champions tour. The duo has together won an incredible 13 Grand Slam titles - in March they will meet for the first time in Sweden.

The ATP Champions Tour could be compared to one big Hall of Fame. The field is exclusive and only former champions will participate. In order to qualify for the tournament, the players must either have been ranked no.1 in the world, be a Grand Slam winner/finalist or a singles player in a winning David Cup team.

Carlos Moya is currently top-ranked in the world, followed by Mark Philippoussis and Thomas Enqvist in third place.

The ATP Champions Tour is played in eleven cities around the world and is normally played over four days in a round-robin format, ensuring that all players feature in at three matches per tournament. There are eight players, divided into two groups of four, where they play against each other in each Champions Tour event. The top player from each group contests the final, while the two players who finish second in each group play off for third place.

The matches are played in best of three sets, with the deciding set taking the form of a Champions tie-break. The winner is the player who first scores ten points and two-point margin.

The ATP Champions Tour is played in: Stockholm, The United States, Switzerland, Colombia, Brazil, Portugal, Belgium, China, Chile, England and Mexico.
