Fabio Vieira, Emile Smith Rowe and Cedric Soares featured for Arsenal U21s side against Swansea U21s in the Premier League Cup on Wednesday night.
Mikel Arteta sought to get minutes into the trio's legs following a disrupted pre-season.
The Gunners won the match 2-1 and Cedric got the scoresheet.
The Portuguese right-back fired a brilliant free kick into the back of the net.
Arteta will now weigh up whether to select any of the trio for Saturday's trip to Bournemouth.
