Real Madrid can replace Vin Jr if they want, but they will need a good and reliable right winger before they can let him go so that Mbappe will go back to his natural position which is the same position with Vini Jr, then should look for a reliable striker that can score plenty goals like Haaland.
Specifically, the problem at Real Madrid is that Vini Jr. is the strongest left winger so far and, with his age still very productive, it would be quite difficult for Real Madrid to let him go. Although, when they saw the offer from the Saudi club, it was truly amazing. However, Vini Jr. himself has stated that he still wants to stay at Real Madrid, even though the Saudi club remains adamant about getting their hands on the main player. They are even preparing a €350 million offer.

All about players transfer is something unique and interesting to discuss, because one of the things that always amazed me is the fact that some will be intending to go for a specific club and another one will be biding heavily for them, its getting more interested to know what the actual fate may come for Saudi Arabia in getting Vini Jr. but where i think the issue may lies is in his own intention also not to leave Real Madrid, i can see the way the Saudi Arabians are fueling the football sector with money and bidding for players they intend to buy, very soon, we are going to see how it will all end.
