Great Britain hope Kyle Edmund can spring a surprise on day one of the final in Belgium and put the visitors within sight of a first Davis Cup victory since 1936.
Edmund will make his competition debut against Belgian number one David Goffin in the opening match (12:30 GMT).
British number one Andy Murray will then take on world number 108, Ruben Bemelmans.
The best-of-five tie takes place over three days in Ghent's Flanders Expo.
A capacity crowd of 13,000 is expected each day, with more than 1,000 Britons due at each session despite recent security fears in Belgium capital Brussels, 35 miles away.
