Josh will complete his three-month loan stay with Cheltenham Town after this weekend's home match against Walsall and has up till now made 10 starts and two sub showings.
He scored on his debut in the 2-2 draw with Stockport County and is said to have played particularly well in the 1-0 home defeat by Leeds United.
Josh is described as an "energetic player who has good close control and an eye for goal". Fellow midfielder Ian Westlake rates Josh highly, comparing his style of play to Gus Poyet, even if he may have to work a bit on his skills to make it all the way.
Westlake, an experienced player, in Cheltenham on loan from Leeds, also says "He can go on to be a really good player, he just needs to know when you use magic and when to give it simple."
Josh joined West Ham from Portsmouth in 2006/7 and captains the under 18's when at home.
Allen says about Josh "He's a lovely lad but more importantly, I know he's a good player."
