I wouldn't have played Broony 3 times in a week but would have rested him against Livi, as I would have definitely played him in one of these next 2 games. Personally I would have preferred to have him on away from home in Europe and had younger legs on against Hibs. But since he played, I'll rest him on Thursday.
I'd start with a more cautious 4-4-2 then open things up as necessary with the 5 subs, although this side is pretty flexible (if weak on the right side - Frimpong could start instead of Bitton or give Christie a res):
Barkas
Elhamed Duffy Jullien (or Ajer if unfit) Taylor
Christie MacGregor Bitton Elyounoussi
Edouard Ajeti
Bain, Ajer/Welsh, Ntcham, Frimpong, Forrest, Klimala, Connell
I might switch to the 3-5-2 versus Hibs.
