Maybe is a little too late to start him against barca. For that, we should have prepared him the whole season by playing him more. I would prefer him to start tbh, but if he fails or gets exposed and we lose because of that, allegri and him will be bashed.
I dont think we builded up his confidence enough to play this game....because of lack of playingtime.
So we better go on with our trued and tested...even if IMO Rugani is better right now.
