Considering our injuries, I expect Licht to be rested for Tottenham and Barzagli at RB vs Lazio. Or Allegri might do the opposite. In any case, Licht won't start both matches.
Dybala could very well start against Lazio, while Higuain will get 20-30 minutes in the second half. Rugani will probably start instead one of Benatia-Chiellini, and Sandro could be rested this time.
Againt Lazio we might see a formation with Dybala as sole striker:
Szczesny; Barzagli/Licht, Benatia/Chiellini, Rugani, Asamoah; Khedira, Pjanic, Matuidi; Costa, Dybala, Mandzukic.
