The Czech Republic are fielding two high quality singles players.
We know how well Vondrousova is playing, although Muchova - a semi-finalist at the Australian Open last year - is playing only her second event since the US Open because of injury.
Swan and Dart can at least boast a 100% record as a team in this competition. They paired up to beat Greece and Slovenia when the Europe/Africa zone pool matches were played in Bath in 2019.
