I think if Mbappe did not perform brilliantly well as expected in Real Madrid, the fault should be that he didn't play as a winger but a striker which is a big challenge for him to switch over to, because it is not easy for a player that is used to using only right foot to start using his left foot because that is what the coach wants.
That’s how the Mbappe performances supposed be for now, because everything is a gradual process. A player can just join a new team and understand how the patterns of the team be with in one month; at least he has to take a long period of time for him to observe the team's well; But for the switch over the position, I think it's not normal because there's know way a player who's using the right foot to switch to the left foot. How is going to balance? Even though that's what the coach wants, it will know go as he deeded.
I believe he just started and will definitely cope and key into the Rolex given to him. He is a world class scorer so giving him the task of a striker shouldn't be a big challenge for him to the point that he will decline in performance.
A time is coming that Mbappe will make positive changes for Real Madrid. Everything deserves enough time to understand. If the guy starts his normal form, everyone will be surprised, so there’s nothing wrong if his performances is not stable for the team’s. Since everyone knows how good Mbappe was be in his former club, that's how is going to be tough in the Real Madrid in fees week time.
