Chelsea have an average squad age of 26, it's the fourth youngest in the league. That number also includes the outlying Thiago Silva. To some extent Cesar Azpilicueta at 33 and Pierre-Emerick Aubameyang, also 33, are anomalies as well.
Of the 11 players that have played the most minutes this season the average age is 27, though. For all the young quality in the squad they aren't getting the minutes needed to develop. This is not just relevant to academy hopefuls like Lewis Hall and Harvey Vale but also for January additions Noni Madueke and Mykhailo Mudryk.
The average age of the starting 11 that faced Brentford on Wednesday was 28. Although there was nothing to play for in the game other than west London pride, which has already gone considering the Blues are 11th after 32 games.
