Hammers stopper Raphael Spiegel has joined Conference leaders Barnet on a month`s loan.
The 21-year-old, who has represented Switzerland at under-17, under-19 and under-21 international level, has been at Upton Park for two years and has played predominantly in their under-21 team.
Spiegel started his career with Grasshoppers of Zurich as a 14-year-old and had loan spells with two other Swiss League clubs, FC Wil and SC Bruhl SG, prior to his move to England when he signed a three-year contract with an option for a further year.
Earlier this season he had a loan spell in Sky Bet League One with Crawley Town.
