To be honest, Juventus' performances appear to be improving these days, as I can see they've won the majority of their previous matches without much challenge, as they try to catch up Atalanta from third place, with only three points difference them; and Juventus's fixed match against Atalanta is coming up next tomorrow; we never know what will happen.
I will not consider Juventus performance as improving because they are so very inconsistent, today they will have a good game and the next they will have a very embarrassing game. This is the reason why I don't think they can win the league.
They should now focus on trying to be consistent and also create more chances. I have watch some recent Juventus games and I thought that they created little chance even though they controlled the game.
