Billy Gilmour could follow in the footsteps of Chelsea team-mate Callum Hudson-Odoi and make his full international debut before he has started a match for his club, according to former Rangers colleague Kenny Miller.
Scotland Under-21 international Gilmour made his Blues debut as a substitute in the 2-2 draw with Sheffield United at the end of August.
Former Scotland striker Miller was at Rangers when Gilmour came through the ranks before his move to Stamford Bridge in 2017.
Miller told BBC Scotland that the 18-year-old “will be one of the best players in the national team when once he gets there”.
Eighteen-year-old winger Hudson-Odoi, who is yet to play this season because of injury, started for England before he had been named in the starting line-up for Premier League match.
