If not for the arrival of Mbappe, Vinicius was the best player in Real Madrid that you can count on whenever Madrid needs a win in any match. You should see how important and good he is at his to the extent that Ancelotti have to convert Mbappe into a central forward instead, of allowing Mbappe play to play on Vini's wing. Vini will not be sold because the club needs him more than the Arab men.
Vini is no doubt an important player for Real Madrid in both Ancelotti and this present Xabi Alonso's era if he wasn't Xabi would've tried to offload him just like he's doing with Rodrygo currently but he has a major role to play for Xabi Alonso when the season start that's why he's untouchable. Real Madrid is yet to bounce back hopefully we'll see a different Madrid when the new season starts, but right now Xabi has lots of work to do in the preseason by drilling his players to improve better and give their best ahead of the new season he also has to use this period to know the suitable positions that would suit soke players and help them do better.
