Krystian Bielik has made his first public appearance since signing for Arsenal.
The Polish teenager was pictured in the stands on Wednesday night at Borehamwood, watching the Gunners' under-18 side beat underdogs Royston Town in the FA Youth Cup.
A brace from Steph Mavididi gave Arsenal a 2-1 victory having gone 1-0 down early on.
Bielik was confirmed as an Arsenal signing earlier in the day, completing a switch from Polish side Legia Warsaw.
He is expected to go into contention for the first team squad, but the defensive midfielder is lacking fitness, Arsene Wenger told a press conference on Thursday, confirming he would not be in the squad to face Brighton and Hove Albion in the FA Cup this weekend.
Watching his fellow teenagers will have been a useful experience for the new addition, and it's likely he will play alongside them, or the under-21 team before turning out for the first team.
Arsenal's under-18 team face Crewe Alexandra in the fifth round of the FA Youth Cup, as they attempt to win the trophy for the first time since 2009.
