England boss Gareth Southgate - on the day that was dubbed Waistcoat Wednesday in his honour back home - named an unchanged side to face Croatia, while Zlatko Dalić surprisingly made just one change from the side that beat Russian Federation on penalties in the quarter-final, bringing in midfield Marcelo Brozović for striker Andrej Kramarić. It's been a fantastic journey.
