Before Shea Charles made his first team Manchester City debut on the final day of the Premier League season at Brentford, he was one of three young Blues who had incredibly played at senior level for their countries before making their club debut.
U21 captain Charles had seven Northern Ireland caps to his name before getting a run-out for Pep Guardiola, while Alex Robertson was given a full Australia debut earlier this year as he waits for a City call - although he has played senior football on loan in Scotland. In the under-18s, left-back Tom Galvez is a senior Finland international, but is yet to make a matchday squad for City.
There could be another youngster close to a senior debut for his country, as attacker Oscar Bobb is impressing at the under-21 European Championships.
