I think mbappe is that kind of player thats good when he is at a particular league side, he is making me to believe that Spanish laliga style of football doesn't fit him, he is struggling to fit into their style, I don't know if I will say he hasn't adapted to Real Madrid pattern of play may be due to the reason that this is his first season there, I don't even know what to attribute this kind lapses to, though we keep watching to see if he will change but it's becoming very serious, though I don't blame him very much for faling to score a penalty for consecutively 2 times like I said earlier in some post of mine, scoring penalty is a luck but more is expected from mbappe as a star and his not giving Realmadrid what they want from him presently, mbappe has failed in different angles, i think Realmadrid might be having a rethink soon if this kind of underperformance of his persist, having problems with PSG and not being invited by his nation as you said shouldn't make him lack concentration in a team that he has always wanted to play in, his country side invitation problem can be fixed but that of his former club i wouldnt know but I think is time for him to concentrate on his career because as it stands his carreer may be threatened if he continue this way.
