Cristian Montano is to spend the next month with Dagenham and Redbridge after joining the League Two side on loan until 17 December 2011.
The Colombia-born forward will embark on his third loan spell of the 2011/12 campaign, having previously enjoyed a successful time at League One club Notts County and a stay at League Two side Swindon Town.
At Notts County, the 19-year-old scored four goals in eleven appearances - just four of them starts - earning rave reviews from manager Martin Allen and helping the club to climb into the League One Play-Off places.
The 19-year-old returned to Chadwell Heath before going out on loan again to Swindon, where he made four league appearances under Robins boss Paolo Di Canio.
Montano, who turns 20 on 11 December, could make his Daggers debut in Saturday's home match against League Two leaders Southend United at Victoria Road.
In all, he could make four league appearances for John Still's side, with a home game against Port Vale and away matches at Accrington Stanley and Burton Albion also to look forward to.
Daggers sit 22nd in League Two, having lost eleven of their previous 12 league matches.
Montano becomes the eighth West Ham United player out on loan, joining temporary loanees Herita Ilunga (Doncaster Rovers), Frank Nouble (Gillingham), Ahmed Abdulla (Swindon Town), Callum McNaughton (AFC Wimbledon), Rob Hall (Oxford United), and season-loan loanees Jordan Spence (Bristol City) and Pablo Barrera (Real Zaragoza).
Olly Lee (Dagenham and Redbridge), Jordan Brown (Aldershot Town) and Dominic Vose (Braintree Town) have also recently returned from loan spells of their own.
