Allegri says that we'll do everything to have him fit for the 2nd leg.
Perhaps he's telling the truth, perhaps these are mind games. Maybe Pogba will be ready for the 1st leg too, maybe we know that he won't make the 2nd leg, or maybe Allegri is being honest and Pogba might be ready only for the 2nd leg.
We won't be able to hide Pogba's actual state for much longer. He won't simply start out of nowhere against Real. He'll first get some minutes in Serie A.
