As England prepares for its first World Cup semi-final in 28 years against Croatia on Wednesday evening, scores of supporters say they will be wearing a waistcoat in Southgate's honour as they cheer the team on.
"I think we've developed very well here, we've showed a good level and had the right attitude, commitment and fight from the beginning", said Dier, who came on in the final few minutes against Sweden.
"We must rest now but I am sure we will have enough energy to face England because there is hardly a greater motivation than a World Cup semi-final".
"It is fantastic to be part of this World Cup so far and I get the feeling from the boys that we don't want to go home". At this World Cup, it has been a case of teasing them in like Trippier and angling them in like Ashley. But personally, I feel Lukaku has been far better than him during the World Cup.
Nearly 20 million people in Britain tuned in for the victory over Sweden, not accounting for the many more who watched in pubs and public viewing areas. He was really good, confident. We want to be here till the end.
Hosts Russia disappointed but exit World Cup stage with pride
It is only the second time that Croatia have reached the World Cup semi-finals since becoming an independent nation. Liverpool's No.6 played the full game in what was a gripping quarter-final tie.
Kane is the heavy favorite as he tries to become the first English player since 1986 to win the World Cup Golden Boot.
Kane is mindful of the influence he now wields as one of the game's top stars, but the status is one he appears to embrace.
"I couldn't be happier for a player - you see his route into the game but all the big clubs will be chasing him when this tournament is over".
Alli was part of the England squad who crashed out of Euro 2016 with defeat by Iceland and he said Southgate had encouraged the players to confront that memory before the tournament.
"They have been playing at an extremely high level for their clubs". We also look ahead and dare to dream.
