No, Allegri is easily capable
That said, he needs to go for it in the first leg & to use his 4-3-1-2. They can dominate that midfield with his diamond if they desire.
But he may play defensive, which would be a mistake imo.
Not hoping for anything. But the Sevilla game showed that against decent sides RM is suffering, Sevilla just couldn't take their chances. Juve hopefully are better and maybe they can score 2-3, because keeping RM on 0 is very very hard and if they score 1, it is better when you score 2 or 3.
