So far this news is only media speculation because basically Vinicius and Mbappe real position is a winger even left winger and because they have same position so there is possibility one of these players will became an substitution players because impossible to playing them together in the same position but i think it shouldn't be a big problem because whether it Vinicius or Mbappe can be played as striker position because in PSG Mbappe currently was so often to played as centre striker and the result is very good because he is Ligue 1 top scorer now even so with Vinicius because while Joselu got injured Ancelotti playing him as a striker several times
So basically Mbappe and Vinicius in the same team will be very good because both players can be played from different position depend on team needed and indeed there is possibility too Vinicius will probably thinking his future in Real Madrid but not because of the arrival Mbappe this because Vinicius was frequent racism in the Laliga and it makes him very uncomfortable to playing with Real Madrid and if this rumour is true i think it's not hard for Vinicius to find new club because some of big clubs has been showing their interest to him one of them is Manchester United
In PSG, Mbappe is one key man that they don't want to give off yet. Even though his contract is set to expire by summer, they still know he's advantageous and would want to keep him. For Mbappe, his stay in the team beyond and after the expiration of the contract seems to be dependent on his intentions as well as the teams performance in the long run.
Good thing for him that Madrid may not really be interested in him yet until summer so he's got to be a bit patient till then, then maybe, he'd be willing to join the Spanish side. Even though Liverpool were questing for him as well, i didn't think they were set to afford that amount for him during the January transfer window. Let's just anticipate summer break whilst watching his movement decision unfold.
Real Madrid has even been performing at their best without a stable striker in the team, then we think of how much more they'd perform if they eventually get a striker for themselves. Left for me, they're doing just fine without a striker. They've in the team a lot of youngsters that are doing excellent in their general balling ability. But still they just have to have for themselves a striker that'd be majored on that role of goal scoring and they won't have to be using a false forward in their games.
Well before now, Mbappe was a prospect but Ancelloti has said for now he won't be making any change to his squad and he's comfortable with them. I believe they have what it takes to get the species of forward they want in the team and the team's commitment and bond would really boost their results.
