Kylian Mbappe should make the move if it's going to be possible, he really deserves it, imagine the trio of Kylian Mbappe, Rodrygo and Vinicius Junior, they'll be unstoppable if they have enough creativity from the midfielder's linking defense and the attackers.
This might be interesting, but it doesn't look like it's going to happen this season. No matter how much Mbappe wants, in the end he will still stay at PSG. There were several factors that made Mbappe stay at PSG and of course this was a tough choice. However, PSG have lost several forwards this season such as Messi and Neymar. So, Mbappe will definitely continue to stay, at least until the contract actually runs out.
Meanwhile, Real Madrid also seems to have no more high hopes for Mbappe after what happened a few seasons ago. Even though they are definitely still interested. Mbappe has always been linked with Real Madrid but continues to fall short. This time, Real Madrid are focusing on finding a better substitute for Benzema who can certainly strengthen their front line. There are still many rumors regarding this.
