All fans hope that Mbappe can perform as well at PSG with Real Madrid. But right now, I think Mbappe is in the process of transitioning to a different playing pattern with a different coach and teammates. Mbappe is a good center forward and has speed, but Real Madrid does not have a game scheme that relies entirely on center forwards. Mbappe's finishing in some matches may not be good, but over time he will get back to his best performance.
Real Madrid has players who are no less good in different positions, including Vinicius, Bellingham, Rodrygo and others. When a team's game does not focus on one player, every other player can score a goal, including defenders and midfielders.
Actually Kylian Mbappe performed not really bad for Real Madrid looking for his goals contribution until 9 games, but he needs time for adapting well and return back to his top perform by consistent scoring goals every match.
Actually Mbappe get helped by good team mates and many players potential create assists for him but until 9 matches Mbappe scored 5 goals and still dominance from penalty kick.
Absent on international break matches, I believe Kylian Mbappe on the top perform when facing Celta Vigo on this weekend and he has potential continue his goals scoring after not scoring goals last match. Have much time for Mbappe adapt well with Ancelotti tactician and recently his performed not really bad looking how many goals scoring comparison with his appearance for Real Madrid in last 9 games.
