Arsenal goalkeeper Wojciech Szczesny featured for the U21s in defeat to Liverpool.
Szczesny started for Arsenal's Under 21 side but could not prevent the visitors falling to a 3-2 defeat against an impressive crop of Liverpool youngsters at Anfield.
The Poland international has not been given a senior appearance by Arsene Wenger for over a month, with Lukas Fabianski being preferred over his error-prone countryman.
