Kepa quickly gets used to Spain. After all, it's a country he knows. I think his adaptation to Real Madrid will also happen quickly. Bellingham's performance is tremendous. I've never seen a new transfer perform like him. He plays as if he can fill the gap in the striker area, which is currently missing in Real Madrid. Ancelotti must be very happy to have him on the team.
Bellingham is getting a lot of credit now because of his performance but I don't think that Real Madrid can always rely on Bellingham for goalscoring matters because Bellingham plays as a midfielder, now we can see that Real Madrid have a lot of quality players in midfield but they are unable to recruit quality strikers in the midfield. transfers this summer, they are too protracted with Mbappe's transfer which has never been clarified.
Meanwhile, Kepa is a Spanish goalkeeper, who used to play for Athletic Bilbao in La Liga. Of course it will not be difficult for him to adapt to the Real Madrid team, we just need to wait for time to see Kepa in Real Madrid's starting line-up.
