Trialists Ade Yusuff and Mawete Nkunga will spend the rest of the week training with the Blues, according to the Tresham Academy where they currently train.
The 19-year-old duo started last night’s 4-3 U21 victory over Colchester and could feature in Saturday’s U21 game at QPR (KO 11am).
Yusuff is currently playing with Banbury Town in the Evo-Stik League Southern Division and has previously been with St Neots Town, Biggleswade United and Stevenage's youth set-up.
Nkunga, known as Jordy, is with St Neots Town, also in the Evo-Stik League Southern Division.
Tresham Academy manager Jonathan Heathcote also works for the Blues as a scout.
