Men's team tennis in a World Cup-style format - haven't we only just had an event like that?
Less than six weeks after Rafael Nadal helped Spain win the inaugural Davis Cup finals in Madrid, the world's best male players will again represent their countries at a rival team competition, the ATP Cup.
Set up by the men's tour with the carrot of huge prize money and ranking points, the new event features 24 teams playing over 10 days in three Australian cities in January.
Great Britain are among the nations competing after Andy Murray, using an injury protected ranking of two, made a late decision to enter.
