Eight teams will contest the International Swimming Federation (FINA) Men's Water Polo World League Super Final, which begins in Ruza in Russia tomorrow.

The sides, who all progressed to the event through European qualifying or April's Intercontinental Tournament, will initially play in two groups of four at the Aquatic Palace.

Olympic champions Serbia are the sport's main force and will be looking to defend the World League title after winning the 2016 Super Final in Huizhou in China.

Serbia are also the reigning world and European champions and have been placed in Group A in Ruza.

They will face the United States, who they beat 10-6 in last year's final, Kazakhstan and Rio 2016 bronze medallists Italy.

In Group B, Olympic silver medallists Croatia will meet Australia, Japan and hosts Russia.

All eight teams will progress to the quarter-finals, with the group stage determining who plays who.

The final will be played on June 25.

The first Group B fixtures pit Croatia v Japan and Australia against Russia. 

"We have inspected the Aquatic Palace and it seems as if everything is ready for the start," said FINA's water polo committee chairman Gianni Lonzi.

"The venue is very nice, it is a great compliment for the region to have such a fantastic sport facility in place, which will help promoting aquatic sports, and water polo among them. 

"The Organising Committee has done a good job, which gives me confidence that the Super Final will be a success."

The Super Final is considered to be the most prestigious water polo prize outside of the Olympics and World Championships.

This year's edition of the latter will take place in Hungarian capital Budapest as part of the FINA World Aquatics Championships between July 14 and 30.
