Arsenal defender Lino Sousa is expected to complete a move to Aston Villa on Deadline Day.
The 19-year-old was due to sign a four-and-a-half-year contract with Villa before going on loan to Championship side Plymouth Argyle.
Sousa was one of a number of academy players who could leave the Gunners either permanently or on loan before the deadline.
Winger Charles Sagoe Jr is a loan target for Swansea. The 19-year-old made his first-team debut for the Gunners this season, coming off the bench against Brentford in the Carabao Cup in September.
Sagoe will have a familiar face in south Wales after Charlie Patino made the same move earlier in the window.
Meanwhile midfielder Bradley Ibrahim, who captained Arsenal to the FA Youth Cup Final last season, completed his move to Hertha Berlin today, with a deal until 2027.
England youth international Ibrahim also featured on the bench for the Arsenal first team this season, the 3-1 Premier League home win over Burnley in November.
Two academy players who shouldn't be leaving Arsenal today are Amario Cozier-Duberry and Reuell Walters. Like Lino Sousa, they have six months on their contracts, but Arsenal want them to stay.
The plan is to continue contract talks with the pair after the window in the hope they stay. Walters is happy to wait until May before deciding what to do.
