Arsenal have confirmed that Michal Rosiak has left the club following the expiry of his contract.
Rosiak, who can play at right-back or in midfield, was offered a new deal but hasn’t signed fresh terms.
The 19-year-old, a Poland youth international, was named on the bench for the Arsenal first-team away to Real Madrid in the Champions League last season.
Rosiak was listed on the club’s official website as one of the academy players that have departed this summer.
