you are not entirely wrong, Juventus last few games have been really poor
Nothing to say about the performances, they are poor and there are no excuses for a team that has only played the championship: Lazio on the other hand are now drained and angry, so the match could reserve some surprises for us. I wouldn`t bet on this match.
I also think that in their match there will be a very interesting surprise because on the one hand Juventus also don't want to lose any more points in the remaining matches. And as bad as Juventus are this season, at least Juventus should be able to stay in that position until the end of the season by never losing again since this week. But if they continue to lose for the remainder of this season, I also doubt Juventus will maintain its position until the end of the season.
As bad as Juventus are in this moment, at least Juventus are still better than Lazio and therefore, even though Juventus are playing away but I believe Juventus still have a chance to win or at least not lose. Indeed, sometimes Juventus get bad results even though they only play against mediocre teams but about playing against Lazio, basically Lazio is also not a weak team at all. Therefore, then of course Juventus will realize the quality of Lazio so Juventus will still try their best, moreover Juventus also play away in this match. So yes, considering Juventus still have to be safe in the top four, then of course Juventus will not underestimate Lazio, and Juventus will try to maintain a good trend against Lazio because Juventus have always been a difficult opponent to beat for Lazio.
