Few players will likely to be every given the privilege of a symbolic final cap for the England national team - but all-time goalscorer and most-capped outfield player Wayne Rooney has never been normal.
It would have been a dream end to a 3-0 win that saw Southgate juggle honouring Rooney and building for the future, with Callum Wilson - one of three debutants - completing the scoring after first-half goals from Jesse Lingard and Trent Alexander-Arnold.
An emotional Rooney, who now plies his trade for Major League Soccer's DC United, told reporters afterwards that the sky was the limit for Gareth Southgate's men. The third one was scored by Bournemouth forward Calum Wilson in the 77th minute.
The heavy rotation was likely with a UEFA Nations League clash with Croatia on Sunday in mind.
Rooney retired from England duty in August, 2017 but the FA chose to turn the friendly into a tribute game to the Liverpool-born forward.
Rooney added: "I think it's great that The FA are celebrating players who have left a mark on global football".
"I really did enjoy that, playing in front of my family and in front of the England fans", said Sancho, who moved to Germany in search of playing time having emerged from Manchester City's youth system.
Under Southgate, England reached the World Cup semi-finals at Russian Federation 2018 and, having spent time in the camp this week, Rooney has seen enough to believe the country's wait for a major trophy - which stretches back to 1966 - can come to an end.
A victory would see England win their group and progress to next summer's finals, but defeat or a score draw would see them relegated to League B.
"When I first came into the England set-up, Wayne was captain and welcomed me and made me feel at home", Delph said, via The Guardian.
"I thought we were too open and a bit ill-disciplined", he said.
England manager Gareth Southgate said: "The players will have taken on board Wayne Rooney's humility, even after everything he has given to the game".
"I actually missed the birth of my second child being out there, so that shows the sacrifices I made to get to this point".
England's record goalscorer came on just before the hour to a rousing Wembley reception for his 120th and final global appearance.
"It would have been ideal for him to score but we saw some moments of real quality from him".
