Defender joins after successful trialReds have today signed defender Danny Pappoe on a non-contract basis.
The 22-year-old former Ghana under-20 international joined the club during pre-season and played in the friendlies against Lewes and Aldershot.
Daniel joined the Chelsea youth set-up in 2010 and played regularly for their youth and reserve teams, which is where Reds' Head Coach Dermot Drummy knows him from. He is a former captain of Chelsea's youth team.
He had loan spells with Colchester and Kingstonian and after leaving Chelsea he was part of Brighton & Hove Albion's development squad.
Last season he played for Hemel Hempstead in National League South.
Dermot said: "Danny has done well in pre-season and by signing this non-contract agreement it gives us more time to assess him and give him an opportunity to show us what he can do. I think he's got a lot of potential and we look forward to working with him going forward."
Danny was registered in time to be available for selection against Wolves in the EFL Cup on Tuesday night.
