Siena still has a chance for Serie B championship, will be only a point behind Atalanta with one game to go. Would be nice if Siena won it. Would be Contes second Serie B championship.
I am not saying that he will be a success, or anything like it. But he has definite talent as a coach, If a coach is clueless his team will never play such good football.
This game shows that Conte is a good coach. It is hard to have a team play such good football, even against Serie B opposition (and also Siena has Serie B players, so the difference in quality is not big).
