Arsenal must move quickly to sign trialist Mason Cotcher.

The Sunderland striker has been training with the club's U18s and turned out for the Gunners' academy team last week.

However, he also is fielding interest from other clubs.

The Daily Mail says Brighton and Rangers are also interested in Cotcher.

The England youth international striker made Tony Mowbray's first team squad for an FA Cup victory over Shrewsbury Town at the beginning of the year.
