Sure. The thing is that Real Madrid wants everything to go as they want; most of them are not interested in any explanation; they just want to see Mbappe's performance, as they know him from his former team. They are forgetting that this is a new team and also a competition that he had not participated in before, so he needs to take his time and understand the style of play and also how his colleagues in the squad play. The Real Madrid fans want a quick result, which I think will be hard to see. All I know is that Mbappe will do well in Real Madrid, but he needs time to understand things first.
Club owners don't want any excuses. This is the reason why they give coaches everything they ask including the best players. Coach Carlo Ancelotti wanted Kylian Mbappé and maybe he told the board members that Real Madrid will be unstoppable if the Frenchman is brought to Santiago Bernabéu. I will start judging the player after ten games. The League is still fresh and he has scored some important goals. Mbappe will be successful in Real if there is a good relationship between the players.
As long as la Liga is concern, Real Madrid are way ahead and with such a mindset, only winning is on their mind right now, because their can't afford to spend such a huge amount of money on player's that could delay or failed to perform and one thing with clubs owner's is that, as soon as the player get signed and paid for, he is task to deliver at each match.
This is the reason why clubs like Real Madrid go for players that are already breaking records in they previous clubs, mbappe is one of such player's and for now a lot of Real Madrid hopes are built around that recent additions to the club.
