Croatia, which faces Portugal in the round of 16, is the Guardian’s top-ranked team at Euro 2016 after the group stage. Luka Modric, Ivan Rakitic and Mario Mandzukic came into thetournament as Croatia’s big stars, but it showed it could win without Modric and Mandzukic, who missed the 2-1 win over Spain with injuries. They trained on Friday and could face Portugal in Lens.
