I think Real really needs to sell Vinícius ASAP. His mentality doesn’t suit the club, and honestly, people are starting to dislike Real Madrid even more because of him. There was a rumor about him going to the Saudi Pro League, but that obviously fell through.
They should put Mbappé on the left wing and give young Gonzalo García a chance up front — the team would be much better off that way compared to playing with Vinícius.
They will definitely gain more by selling Vinicus for sure.

Why, I think you're just fed up with Vinicius Junior. But honestly, he is not that bad to be kicked off from the team because before the arrival of Kylian Mbappe, he was the one who have played brilliantly and driven his team towards the UEFA Champions League title. Vinicus Junior is good player but right now the team is feeling an imbalance due to too many stars in the attacking area. If Xabi Alonso makes any better posture for the team attacking, then probably these two can make a good spike in the team performance.
Yeah, it's true that Saudi Arabia clubs are pushing hardly for Vinicius Junior, but I don't think Perez will let him to go to the Saudi Arabian side because right now he is a key player of the Real Madrid team, and also he is too young....
I don't think it's that easy to sell Vini to another team, because not only is his price high, but Vini also seems to want to stay at Real Madrid. So, given that, it's clear that Vini will be difficult to sell to any team at this time. Therefore, in my opinion, Real Madrid must take a more intensive approach with Vini so that Real Madrid and Vini can find a middle ground to resolve this issue. Because if, for example, Real Madrid were to lose Vini, I think that would clearly not be a good idea,
Because even though Real Madrid currently has Mbappe, that wouldn't solve the problem either. Because Mbappe's position has already shifted to the front line, and it seems he's already quite comfortable with his new position. So, given that, Vini will still be needed on the left wing at Real Madrid. For that reason, it is highly unlikely that Real Madrid will sell Vini. Because, fundamentally, the issue Vini is facing right now isn’t about his position but about his salary, which he is requesting to be increased. And I am sure Real Madrid will be able to overcome this problem.
