Don't you think it's seemingly early to be talking about all of this already, mbappe is apparently doing his very best and Madrid hasn't been faced with any less of challenges, you should also understand he's not the only player in the team and wouldn't be the only person to make all the goals and win the game,  he will be needing his team mates to assist him and if they are challenged with injuries and some inconsistencies, it will affect his productive rate, so mainly that could be one of the challenges he may be facing at the times, just maybe Madrid may bounce back and all of this would be something we will not be thinking about again as they will make good attempts at all the prestigious trophies.
