Arsenal midfielder joins on loan.
Colchester United have made their second addition of deadline day, with the signing of Arsenal midfielder Glen Kamara.
Glen follows Reading winger Tarique Fosu in penning a loan deal with the U's and he too will initially be with the Weston Homes Community Stadium side until the January transfer window.
The 20-year-old - who was born in Finland and has represented his country up to U21s level - began his career in England with the U's Essex neighbours Southend, but joined Arsenal in 2012.
He has played once for the Gunners' senior side in the League Cup in October 2015, before returning to Southend in the second half of last season.
His six appearances for the Shrimpers included 45 minutes in the Essex Derby at Roots Hall.
He will now pull on the blue and white of the U's, once he has returned from Finnish international duty.
