But new call-ups Sancho, 18, who signed for Borussia Dortmund a year ago, and Mount, 19, who spent last season on loan at Dutch club Vitesse Arnhem from Chelsea, have shown the benefits of going overseas.
TEENAGERS Jadon Sancho and Mason Mount have urged other rising English stars to move in search of regular football at home or overseas, insisting their call-ups to the senior squad this week prove it is a risk worth taking.
"I think it's vital [to be playing] because not everyone wants to play U23s".
"I'm learning German, of course".
He will be hoping to make his bow for Gareth Southgate's team in upcoming UEFA Nations League games against Croatia and Spain, while the Young Lions appear destined to be heading to next summer's European Championship in Italy.
"The Champions League is the greatest stage, so I hope the young players reach their potential and enjoy it too".
"Sancho's progress has been very, very rapid", said Southgate.
Christian Pulisic, the United States of America worldwide and a Dortmund team-mate, has been a big influence: "He is another young guy, and I learn from him".
He has not only proved himself to be stunning with his keen dribbles; he is also wonderful at power shots and deft through balls and key passes which makes him one of the best young all-round players in Bundesliga now.
Jadon Sancho, 18, and Mason Mount, 19, who made moves to get more first team football, and James Maddison, who jumped to the Premier League, are all rewarded with a first call-up.
"But that won't faze me at all".
The World Cup victor told The Sun : "He is a natural footballer, who loves to play on the left wing but has unbelievable talent". If you're ready to play overseas and you believe in yourself, why not?
"That's. I don't know".
Sancho has told the London Evening Standard that the rumours of a £100million valuation are "mad", but did leave the door open to a return to England at some point, even if he is happy at Signal Iduna Park right now. "It's the future. You never know what could happen, so we wait and see". Sancho has shone playing on the left of midfield, racking up a mind-blowing nine assists for BVB already this season.
Similarly, the opportunities for young players are there in France and Germany.
