Sweden are the only country to make a move in the latest edition of the Nations Cup after Robin Soderling's triumph in Paris.

WHAT IS NATIONS CUP?

The Nations Cup is a ranking system that assesses the performances of tennis players of both genders from a specific country - the nation with the greatest overall success over the course of the season will be declared the Nations Cup champion.

See the 'How it works' section below for a full explanation of the scoring system.

The standings

Robin Soderling's victory in Paris on Sunday not only secured him his first Masters Series title but also sees Sweden move three places up the Nations Cup rankings.

And that is pretty much it: with only one tournament in action on either the ATP or WTA Tour, there is very little change to the rankings.

France picked up runners-up points in Paris as Gael Monfils was beaten by Soderling in the final.

They also scored from Michael Llodra's run to the semi-final, but it was not enough to see them overtake Switzerland as Roger Federer also reached the last four in the French capital.

So Switzerland remain in sixth, with France a further 90 points behind in seventh.

HOW IT WORKS

Players are awarded points for reaching the semi-finals or further of a tournament with the total number of points for each player then being added to their country's tally.

The number of points awarded are weighted not only to reflect how far a player progressed (with the tournament winner receiving more points than the runner-up and more again than the beaten semi-finalists) but also to reflect the difficulty of the tournament.

Thus a Grand Slam win will earn a player 200 points, a Masters series win 100 points and so on through the four tournament categories.

And just to add to the confusion, a country will also be awarded bonus points if they provide both finalists at a tournament.
