There is no doubt that Mbappe is a talented player. But adapting to the new environment and new match strategy of La Liga is a bit difficult. Moreover, Mbappe's position at Real Madrid also had to be changed. Because of these reasons, Mbappe's performance is somewhat erratic. But Mbappe is very talented. He will surely adapt himself to this squad very quickly.
Mbappe and Vini do not have a friendly relationship. Moreover, Bellingham, one of Madrid's most important players, is not in the squad yet. Bellingham's return to the squad will surely stabilize Madrid's performance.
The most noticeable is the change in his position as a striker at Real Madrid. Indeed, previously at PSG, Mbappe was used to filling that position several times, but again his original position is a winger and the transition to changing positions will take quite a long time. Having a partner with the same quality as him also does not guarantee that he will be able to maximize his talent more easily and this requires extra patience before everything mixes together.
Talking about the duet of Mbappe and Vini will remind us of the previous one where Benzema was always served by Vini with his assists and if these two players contribute to each other through assists and goals, the amount will be very large each season. Bellingham will be the main axis in leading the attack and his role in finding empty boxes will make it easier for Real Madrid to have a greater chance of winning.
