Jadon Sancho has admitted his inclusion in the senior England squad came as a surprise, despite his impressive form this season.
Sancho was handed a first call-up to the England squad last week by manager Gareth Southgate and was named on the bench for the trip to Croatia.
BVB paid a knockdown £7m in compensation to Manchester City for Sancho in the summer - yet he is already being linked with a quick return to the Premier League.
It'll be more playing time, at a club with a history of nurturing young talents, that allows Sancho to fulfil his masses of potential, develop further and, in the fullness of time, secure a move to a European big-hitter.
"It would be a dream come true (to make my debut against Croatia)".
"You just want to go out there and do your best and I'm sure everyone will. I just couldn't stop smiling for the whole day".
Promising England youngster Jadon Sancho has the capabilities to deal with the pressure that comes with playing for England according to Everton attacking Theo Walcott. As I can testify, living in a foreign country takes you way out of your comfort zone.
Much has been made of the decision of Southgate to dip into the Championship to pick out Mount, but anyone who has seen the teenager play this season will be in little doubt he deserves the chance to shine.
Jadon Sancho rejecting a new £30,000-a-week contract at Man City to join Dortmund
"I was at training when I first got the call-up", he said. "That's what he said to me".
Sancho joined City from Watford's academy in 2014 for a fee of around £66,000.
The attacking midfielder's performances have recently been rewarded with a contract extension with the German giants until 2022 but living overseas has brought challenges. The setting is flawless for Sancho and a move away at this stage does not have the legs to be supported by logic right now. Leaving my mum behind and my sisters.
He has the ideal combination of talent, potential and big name recognition in the American market to make him a prize asset for any club willing to stump up the huge transfer fee.
"But if you're ready to play overseas and you believe in yourself, why not?"
"That's mad!" Sancho said with a laugh when told of that figure. I don't know what to say'. You never know what could happen, so we wait and see.
For now, his focus is on global matters.
Sancho got the same award at the European Under-17 championships past year, as well as being part of the squad that won the Under-17 World Cup, although his participation was limited after being recalled by Dortmund halfway through the tournament to play for the first team.
