Brentford travel to Birmingham on Wednesday night and they will be looking to claim bragging rights over their former charges, Jota, Harlee Dean and Maxime Colin.
The game is a bit too early for Lewis Macleod, who is a couple of weeks away from being in the squad while Alan Judge and Rico Henry have long-term injuries.
The other question marks for Smith are whether he continues with the Andreas Bjelland-John Egan partnership or brings Yoann Barbet back into the side.
Going forward, he will have a choice between giving Lasse Vibe a third straight start after he was taken off in second half stoppage time after an energetic display or bring Neal Maupay into the starting XI.
