Plenty of players will be looking to prove themselves as the Whites hope to continue the strong start to their Australia tour made by a 2-1 win over A-League club Brisbane Roar.
Fans travelling to the Suncorp Stadium to take in the Villa clash can expect to see lots of old faces and a few newer ones, as Jesse Marsch works on integrating his six summer signings into the squad.
At an open training session on Saturday, the American called on supporters in the stands to get behind United as they go toe-to-toe with some of this season's direct opponents.
Here's how we think Leeds could line-up against the Birmingham side....
7. CM - Tyler Adams
Didn't get a start on the Gold Coast in his first friendly appearance so might well come in for this one. Photo: Chris Hyde
8. LW - Luis Sinisterra
Played just 30 minutes against the Roar so is likely to be in line for a bit longer against Villa. Photo: Chris Hyde
9. RW - Dan James
Only played the first 30 minutes on the Gold Coast so is in line for more minutes on Sunday. Did very well with his cameo, too. Photo: Bradley Kanis
10. CAM - Brenden Aaronson
Marsch has Greenwood, the probably fit Gelhardt and Rodrigo but Aaronson is due more minutes having missed the Blackpool game. Photo: Bradley Kanaris
11. ST - Patrick Bamford
The centre-forward will likely play 45 minutes or an hour after being rested for Saturday's training session. Photo: Patrick Hamilton
