Leyton Orient have handed new deals to youngsters Steven Alzate and Josh Koroma after impressing at youth level.

The pair have signed two-year deals after their fine form in the club's development sides, with Alzate on the bench for their Checkatrade Trophy win against Stevenage last month.

The midfielder has scored four times for the club's Under-18 side so far this season, and contributed a number of assists.

Koroma, 17, has already made his Orient first-team debut, first featuring at Barnet in April, and has gone on to make four apperances in an O's shirt in his short career.
