World number 16 David Goffin will lead Belgium when they meet Great Britain in the Davis Cup final next week.
Goffin is joined by Steve Darcis, Ruben Bemelmans and Kimmer Coppejans, with captain Johan van Herck able to name his strongest line-up.
Goffin, 24, has won 11 of 13 Davis Cup matches, while Darcis looks likely to continue as Belgium's second singles player.
The Great Britain team, led by Andy Murray, was named earlier on Tuesday.
Belgium have not featured in the Davis Cup final since losing to Great Britain in 1904.
