Where does the Manchester United link come from?
Ivica Zubac has not said in his own words that he roots for Manchester United. The tie comes from MUFC Info, which wrote that "Zubac's support for Manchester United is often showcased through his social media channels". That is another outlet's description, so it counts as a background tie, not a fandom he has stated himself.
Does it line up with where he grew up?
Zubac was born in Mostar, Bosnia and Herzegovina, on March 18, 1997, and grew up in Čitluk, just east of the Croatian border, according to Wikipedia. His early career was spent with Zrinjevac, Cibona, Gorica and Mega Leks before the Los Angeles Lakers drafted him in 2016. Nothing in those details connects him to Manchester United, so the club does not trace back to any team he played for or any place he lived.
