It was kin dog expected because Juventus is playing draws almost all the time. No goals was unexpected, I agree. Pretty weird. But Juventus is conceding hardly any goals, scoring any goals. In a certain sense, it was almost predictable.
Talking about defense then I can say Juventus is the team with the most solid defense in Serie A. They have only conceded 7 goals in 12 games. But it seems they can't take advantage of that. They have 7 draws and 6 wins without a defeat. I don't know if they are struggling to create chances or they need a playmaker or a striker with good finishing ability. This is a problem for Juventus because they should have got a better result. But for now I think this is a fair result for both teams. They have equal statistical records in this match. And yes it seems both teams played at a slow tempo in this match.
