Real Madrid players are not playing as a strong team, their performance in La Liga has been poor since they began the league, we never expected Real Madrid to perform this way with the players they put together, everyone expected Real Madrid to score at least three goals against Mallorca in their last two games, Madrid drew 1-1 against Mallorca, a team that lost their last game against Osasuna, and Real Madrid failed to win them.
IMO, Real Madrid is surely strong team, but they played disorganized. If you checked their stats in each match, they always dominated the match and made many shot attempts. Unfortunately, they failed to play as expected. The match against Mallorca is a perfect example, Real Madrid played with full team but ended up the match with unsatisfying result. Real Madrid missed the midfielders who can give accurate assists and their attackers looked playing more individually. However, we must admit Real Madrid looks playing lack of teamwork. This is actually the problem facing by Ancelotti now.
I don't believe playing Mbappe as a striker would produce the results we anticipate from this team since Mbappe cannot stand at the position, he is likely to move to winger because he doesn't seem to be comfortable playing as a striker.
Mbappe may try to adapt with his new position as a striker. But he has a capability as a striker, there is no problem with his current position in Real Madrid. Something missing from Mbappe is his accuracy in shooting. He has many opportunities to score goals but he missed the opportunities. I think it is only about the time, he should be comfortable with his current position in the next few matches.
However, many people blamed Bellingham in their first game that he was selfish with the ball and wanted to score by himself and look at their performance in the first half against Valladolid.
We can't judge Bellingham based on 1 match only. In the previous matches, I saw no problem with Bellingham attitude. He even becomes one of the players who often give assists to Mbappe. He knows how to play in his new role, we don't blame him because he sometimes tries to score goals. Every player has the right to score goals if they have a good chance.
