Muslims worldwide generally support other Muslims. This is why the likes of Khabib, Islam and other Dagestani/Chechen fighters get warm receptions in the UAE, so much so that it is considered a home venue for those guys.
Muhammad Ali was similarly an icon throughout the Muslim world and so are Benzema, Salah and Hakimi. In fact, the entire Moroccan team received support and love from the whole Muslim world (with the exception of one particular region). Moeen Ali, Hashim Amla, Usman Khawaja, Mohammad Siraj, etc are all well-liked and respected in Pakistan because of their faith.
Were you not here when an eminent member of Pakpassion made the famous quote "I hope Pakistan wins the match but Hashim Amla scores a hundred so his average is not disturbed" during a Pakistan-South Africa game.
This is because in Islam we have the concept of Ummah and are commanded to be happy for the success and blessings given to other Muslims and Islam as a whole.
This is the reality and it is a positive thing. It eliminates racism and focuses human tribalism on something that you can choose instead of something you are born with (skin color, heritage).
