Blades youngster Otis Khan will represent Pakistan in 2018 World Cup qualifies later this year.
The 19-year-old, who made his first-team debut against Crawley Town last March, qualifies to represent Pakistan through his grandfather.
The teenager says he is 'excited' by the opportunity to play international football and is looking forward to the preliminary round draw which is made next week.
Khan was also called up to play in a friendly against Afghanistan this week, but was unable to travel to join up with his international team-mates owing to not having time to get the necessary injections and sort out his visa.
But the teenager believes it will be a massive honour to represent the country of his grandparent's birth, he remarked:
"I am very excited about the chance I have been given to play for the Pakistan national side. Three scouts came to watch me earlier in the season in the U21 fixture against Sheffield Wednesday and they said they would be in touch in the future.
"Since then I have had emailed dialogue with the manager and I am delighted to be in the reckoning to play in the qualifiers in April.
"It is a massive thing for me to look forward to and it will be a very special moment the first time I pull the Pakistan shirt on.""
