He ended up playing in both of the Three Lions’ opening two Euro 2020 qualifying matches, as a substitute against Czech Republic before starting Monday’s 5-1 win over Montenegro, and impressed with his no-fear attitude, attacking threat and even played a hand in a goal in each game.
And, given his success in a senior shirt, Boothroyd has admitted he is unsure if the winger will ever return to his Young Lions squad.
Joining talkSPORT on his side’s matchday against Germany U21, Boothroyd explained how the teenager’s promotion came about.
He told Jim White: “I was in the middle of a press conference and then I got a call from Gareth, so I stepped out and took it and he said, ‘we need to take Callum’.
“So I went over to see Callum, who had just arrived and was just having his dinner, and I just said to him: ’Listen I’ve got some good news and some better news. The good news is you’re up with the senior team, the better news is you’re definitely coming back with me in the summer!’
“Now, whether he is or not after last night, that’s between Gareth and myself, we’ll have to have a chat and see what’s best for him.
“But that’s how it all came about. He came and he went. It was a very fleeting under-21 debut, he just got his dinner and left!”

Gunners winger Nelson has six goals in seven games on loan with Hoffenheim, while Sancho’s five goals and eight assists for Dortmund has seen him called up to the senior England team for the first time this season.
But they are not alone – Boothroyd has a host of players all enjoying more prominent roles with oversees clubs.
And he has urged other young players who are struggling for regular game time to think about moving to Europe, telling talkSPORT: ‘It can only be a good thing’.
Speaking on the Alan Brazil Sports Breakfast, Boothroyd said: ”Because the players are not getting in the first-teams of the clubs at the top end, they’re thinking, ‘where am I going to play my football, where am I going to get my games, where am I going to get my experience?’
“We’ve currently got five players who are playing away from the Premier League, but they’re all getting experience.
“We’ve got a couple in the Bundesliga, one is Serie A, one in Ligue 1 and a couple in the Eredivisie in Holland.
Young England players in Europe:
Jadon Sancho – Borussia Dortmund (capped at U19 and senior level)
Reiss Nelson – Hoffenheim (on loan from Arsenal)
Jake Clarke-Salter – Vitesse (on loan from Chelsea)
Sheyi Ojo – Stade Reims (on loan from Liverpool)
Patrick Roberts – Girona (on loan from Man City)
Ronaldo Vieira – Sampdoria (Signed from Leeds for £7m in July)
“So we’ve got players who are being brave and are learning different football cultures and different ways of playing, that’s what they’re having to do to get to where they need to be.
“As long as they end up back in our league, I think that can only be a good thing.”
Midfield playmaker Foden has been tipped to follow Sancho and Nelson in a move oversees, as he struggles for regular game time in Manchester City’s star-studded side.
