Mateo Kovacic has four Champions League medals, four Club World Cup medals, three UEFA Super Cups and one Europa League winner's medal. He has league titles in Spain and Croatia, and helped his country to the World Cup and Nations League finals.
If he retired now, he would have a personal trophy cabinet that few players in the world could rival. On his arrival to Manchester City, though, he is giving no thought to what he's already won.
Instead, he's only thinking about what there still is to win - the Premier League, and more titles over the next four years.
