I hope they will be able to improve their performance. Because if they keep performing like this, it is going to be a problem. this was the first loss for Juventus this season by the way. they had been performing pretty well so far, however in this match, probably it was just a bad day for them. They will play Lecce in the next match, I really hope that they will be able to do better than this in that match.
In their next game against Lecce I'm very optimistic Juventus will not allow that which happened between them and sasuolo repeat itself as they need that win to climb up the table. It was only mistakes that cost them that game which I'm sure to a great extent Juventus will not make such mistakes again as they will improve to make sure they win.
The last game Lecce played was against Genoa where they won by one goal (1-0) the did well in that match but I still don't see them matching up with Juventus except they will only try to make it not a very easy win for Juventus but they will be at disadvantage as Juventus is hosting so the will definitely have that home advantage and would not want to suffer a second loss at home.
