Why Manchester City have not named Phil Foden in Champions League squad

Manchester City named the 21-man squad for the upcoming Champions League group stage games. City's first Champions League game of this season will be against Porto on Wednesday, October 21. City fans may have been questioning Phil Foden's absence from the 'A list' of players, however the player didn't need to be included in the "A list" as he qualifies to be included on "B list", which is for young and club-trained players. Manchester City's next Champions League game after Porto will be against Marseille on October 28. They will also play against Olympiacos on November 4. source - Manchester Evening News
