PRAGUE (AP) — With Roger Federer and Rafael Nadal at the Laver Cup team tennis tournament, expectations are running high about the chance of seeing the two as doubles partners.

The three-day competition kicks off Friday, pitting a team of the best six European players against the top six from the rest of the world. The tournament is to honor Rod Laver, an 11-time major champion who won two calendar-year Grand Slams.

It will include three singles and one doubles match every day.

Federer and Nadal were clear about their choice of a possible partner. Federer said he "would love" to play with Nadal, while Nadal said "it would be amazing" to join Federer.

Europe captain Bjorn Bjorg has yet to decide.
