The budding rivalry between Carlos Alcaraz and Novak Djokovic will be renewed in the group stage of the Davis Cup finals next month.

The 20-year-old Spanish tennis player and Djokovic were included in the teams announced this week by Spain and Serbia, respectively, for the competition that will be played on September 12-17 in Valencia, Spain.

Alcaraz defeated Djokovic in the Wimbledon final in July. The Spaniard is No. 1 in the world, with Djokovic sitting at No. 2.

Spain and Serbia have been drawn in the same group along with the Czech Republic and South Korea. Group stage matches will also be played in Bologna, Italy; Manchester, England; and Split, Croatia.

The top two teams in each of the four groups will advance to the finals in Malaga, Spain, in November.

Alcaraz will lead a Spain team that will include Alejandro Davidovich Fokina, Roberto Bautista Agut and Marcel Granollers.

Djokovic’s Serbia will also have Laslo Djere, Miomir Kecmanovic, Dusan Lajovic and Hamad Medjedovic.

Nine of the current top 20 players in the world have been called up for their national teams — Jannik Sinner and Lorenzo Musetti for Italy, Frances Tiafoe and Tommy Paul for the United States, Alex de Minaur for Australia, Cameron Norrie for Britain and Borna Coric for Croatia.

Andy Murray will also play for Britain, which faces Australia, France and Switzerland in Manchester. The Swiss will count on Stan Wawrinka, while France will have Adrian Mannarino and Nicolas Mahut.

Leo Borg, son of 11-time Grand Slam champion Bjorn Borg, was included in Sweden’s team that will face Canada, Italy and Chile in Bologna.

Mackenzie McDonald, Austin Krajicek and Rajeev Ram were also included in the American team that will play against the Netherlands, Finland and host Croatia in Split.
