Ultimately I believe that the Juventus management can be satisfied with what Allegri did with what he had at his disposal.
Moreover, this season Juventus only plays in the domestic league but yes, in reality it is still not easy for Allegri to bring Juventus to become strong in Serie A. With results like that, of course Allegri must be able to work even better if he wants to get the Scudetto in this season because yes, in fact Inter is still better than Juventus so far this season.
I am supporting Juventus as well this season. They were like the PSG of Serie A a few years back but recently they lost their touch. Didn't qualify for the Europa League or Champions League for a few seasons and they had lost their touch. But this season they are making a great comeback. After beating AS Roma, they are in the 2nd while Inter Milan is in 1st.
Things are not looking good for Inter Milan though. They have tough fixtures coming up in the February which includes UEFA Champions League, and their match against Juventus which might decide who will win the Serie A at this moment. But when they should have been increasing the gap between Juventus and them they reduced it by drawing to Genoa. With this tough fixture, I don't think they can keep up. Juventus might just win the league this time. Last season Napoli dominated the league and it had no fun but this season things are getting very spicy.
