How do FUT Heroes work? FUT Heroes are a new addition for FIFA 22 and will help you build more varied squads, but are not as impactful as ICONs. While ICONs can be added to any team, FUT Heroes are each assigned to a league, so will have a strong chemistry link with all other players from that league. The nationality of the FUT Heroes will also give chemistry boosts, in the same way that all other cards in FIFA Ultimate Team have a weak link with other players of that nationality. For example, Diego Milito's FUT Heroes card will have a perfect link to Lautaro Martinez as they share both nationality and league.
