U 23 is a misnomer - as far as Villa are concerned - here is the current age group breakdown:-
22 - 1 player - out on loan (Lyden)
21 - 3 players (Sarkic, Taylor & McKirdy)
20 - 7 players (inc 2 out on loan)
19 - 12 players (inc 2 out on loan)
18 - 4 players (incl 3 of our first choice U23 defence)
17 - 10 players (several of whom have made the U23 bench)
16 - 1 player (sub GK in the recent BSC match v Coleshill Town - 17 tomorrow)
The average age of the team that destroyed Bristol City was just over 19 - yet theoretically Grealish is still qualified to play. !!
