It is believed that Mbappe likes to play as a left winger/striker who is under the striker (false nine, to be honest I don’t know what it’s called correctly in English). Therefore, the transition to the position of a pure striker may require special efforts from Mbappe, but in the end, a roughly similar transformation when moving to Real happened with his idol - Ronaldo, so Mbappe will be able to repeat this path.
I'd like Mbappe to play in a diverse position, not only focus on one position as a center striker. Importantly, mbappe can be served as a temporary backup if one of his teammates gets injured. Real madrid has ever encountered the situation when Vini and Rodrygo were injured, and Real Madrid had no good wingers to replace them, except brahim diaz. Mbappe can be very helpful when madrid will encounter the same situation.
Mbappe's statistics, on the other hand, demonstrate that he continues to focus on playing as a center striker, which demands him to put in more effort. That was also the primary reason Real Madrid signed him as a striker, not as winger. All in all, mbappe can still provide a temporary solution for real madrid once one of their wingers were injured.
It is clear that if there are injuries, Mbappe can play in at least three positions, but now his destiny is only as a central striker. He will definitely be ahead of Bellingham, Vinny or Rodrigo. Let’s say if Haaland played in Real Madrid, Mbappe could play lower, but in this lineup there are no options at all that Mbappe will not play as a central striker. By the way, I don’t quite trust the statistics (by amplua) since it don’t see the difference between the center forward and the striker underneath, but it see the difference between the striker and the winger, although the second striker can play lower than the wingers.
