Lazio vs Juventus will be a tight match. Both teams perform very well currently. Although Lazio is in 2nd place, I don't think that Lazio is better than Juventus. Juventus is just unlucky because he got a problem, so they lose many points. But if we consider the squad quality, I think Juventus squad is much better than Lazio squad. I really expect that Juventus to win this match, they have good motivation to return to top 5. If they win this match, I assume they may return to top 5 at the end of the season.
Lazio can not be underestimated. Lazio beat Napoli 0-1 at home to Napoli. Lazio also beat Roma 1-0. against Juventus, the chances are 50:50 I think, but Lazio has the competence to beat Juve.
Juventus did well, but Lazio had a more consistent performance. even though they didn't win big, Lazio consistently collected winning points, that's what made them in 2nd place in the Serie A standings.
Truly, the performance of Lazio has improved, especially in the last 5 matches. And this is against the reduced performance of Napoli, particularly at the time that Victor Osimhen is not playing. Also, I believe that Napoli has relaxed, maybe it's because of the points they have now, thinking that no club could meet them anymore this season.
As this is true, I believe they should still be serious, and if Victor Osinhem did not play, they don't have the chance of winning, if he does, they might win against Lazio.
