World Cup proposals

Novak Djokovic says the world's top male players are to consider proposals for a biennial World Cup that would threaten the future of the Davis Cup.

The Serb said the idea for a 32-nation event came from the ATP Player Council, of which he is a member.

"It's all fresh and it's all ideas... we have to consider other sides as well," said the world number three.

Players are set to discuss plans for the 10-day male-only tournament at next week's Australian Open.
According to The Times, World Cup matches would be shorter and, with a maximum of 25 seconds allowed between points, players would have to watch the clock.

Teams would consist of three players and a captain, with the 32 nations split into eight groups of four and 16 reaching the knockout stages.
