I think the team is going to be a balancing act between risk of injury and putting out a strong team.
Ferencevaros has the same uefa coefficient points as Qarabag, and have won all their first 6 Hungarian league matches but lost to Anderlecht 2-1 away in their first EL match, which means that we would be unwise to be too much weaker than the team we put out against Qarabag
Vicario, Gray, Dragusin, van de Ven, Davies, Bissouma (Bentancur 71), Sarr, Bergvall (Udogie 12), Johnson (Kulusevski 46), Solanke (Moore 85), Son (c) (Werner 71). Substitutes (not used): Forster, Austin, Pedro Porro, Maddison, Lankshear.
With Dragusin out and a need to protect Van de Venn's hamstrings, our back 2 will need to be Romero and Gray, RB Porro, and probably Davies at LB.
Midfield is not a real issue - perhaps Bissouma, Bergvall and Sarr.
Attack is, I can see Johnson/Kulusevski each playing a half at RW, Solanke starting but Lankshear coming on after 60 mins, with Werner starting as LW, possibly Son on for 30 mins to add to our goal threat. Moore might be a sub somewhere too
