England manager Gareth Southgate knows his young squad have come a long way since paper aeroplanes were thrown onto the Wembley pitch – but warned the World Cup semi-finalists must continue to improve.

Southgate's side face Spain in their opening UEFA Nations League clash tonight. "Over the summer [at the World Cup] you are looking for results, now it is about developing the team and improvement, looking at how we play, the tactical detail and testing ourselves against some really top teams," the England manager said.
