In as much as it's expected of Kylian Mbappé to hit the ground up and running in his scoring of goals at Real Madrid and starts performing as expected, but it still very early to expect that such performance from him, despite his an incredible player that wouldn't find it very difficult to adapt and blend into any team which he finds himself, Mbappé has just had few weeks play time at Madrid, to me, I won't expect much now from him and until after his first season at Madrid, but if he does performance well, then good.
To whom much is given much is expected. Normally Mbappe is not the kind of player that will go come into a team and still need like a year or more to settle in. He is the kind of player that people expect to hit the ground running immediately with hat tricks and assists. Real Madrid bought him with the intention that he will start delivering goals immediately from the first game. The expectation on him is very high and it's quite a weight for such a young man like Mbappe to carry. Either ways he has to live up to the expectations because he has been doing it for years for both his former club and country. Not many football fans understands the fact that players do need time to adapt. Majority of the fans are not patient, if Mbappe don't start delivering goals and assists soon we might see some Madrid faithfuls turning against Mbappe. So Mbappe should have this in his mind and start putting more efforts.
