"For everyone out here following us and everyone back home - it is special".
Southgate has been just the voice of reason England have needed to prevent anyone from getting too carried away. "We prepare the same way for every opposition".
"The age of the players, the improvement in the players and the hunger of the players has been apparent for everybody to see". We believe we have to continue doing that, to constantly evolve and improve. It will be a battle again but I trust us.
Southgate pointed to the uniting effect the team's exploits have had on a nation enduring "difficult moments" economically and politically, with the seniors threatening to emulate the achievements of England's under-17s and under-20s, both now world champions, and the European Championship-winning under-19s.

Hopefully they can continue to grow and learn on the biggest stage.
