Other than Bailey & Onana, maybe JJ name a single starter in that squad.
A sprinkling of bench players/subs (Barkley/Emi2/Maatesen/Ned) and the rest were youth players. Of course they don't play as well as our first team, possibly because they aren't anywhere near the first team?
A bigger challenge would have seen a different line up.
I can't imagine the League Cup is a huge priority. Nevertheless through to the next round, most of the first team rested and some good mins for Emi, JJ and Bailey, as well as debuts for several youth players.
Mission accomplished.
