Because she isnt scoring the clutch points, especially the OOS, when the contribution of your OPP matter the most. According to the commentators, she is the top scorer of Novara, but not with a good effiencty (below 40%). She is still playing much, much better than in other matches during this season, but still below her standards. We all have seen her smashing and smashing difficult balls, especially with Polska NT.
Novara had at least 5 set points with her attacking for the 0-2, but she was dug, blocked (not kill blocked) or easily passed the ball.
Zanette isnt an option for this kind of matches, so the only option would be to play with Herbots/Daalderop as OPP.
It is obvious Lavarini is trying to give her confidence, cuz once she is confident, she can be super dangerous.
