Youth or experience? Quarter-finalists’ average ages?

From the team whose outfield players had an average age of 22 in the round of 16 to the side pushing 30. Who are the youngest and oldest sides left in the competition?

Monaco’s triumph over Manchester City in the round of 16 second leg was remarkable in many respects, but largely hidden was this gem of a fact: eight of the side that lined up were 24 or under.

ASM’s goals came from Kylian Mbappé (18), Tiemoué Bakayoko (22) and Fabinho (23). Bernardo Silva (22) and Benjamin Mendy (22) caught the eye. For a spell in the second half, when Almamy Touré (20) replaced Andrea Raggi (32), the outfield had an average age of 22. No wonder goalkeeper Danijel Subašić, 32, says he feels like he’s at the creche some days.

At the other end of the scale, Leicester (28.28) and Bayern (28.41) have experience on their sides but both are put in the shade by Juventus. The Italian champions, on course for a sixth straight title, average 29.55. Their 30-somethings include Gianluigi Buffon (39), Andrea Barzagli (35), Dani Alves (33), Stephan Lichtsteiner (33), Giorgio Chiellini (32) and Mario Mandžukić (30).
