The fiery Czech defender came to Upton Park from Fiorentina for £5million back in September 2001 and is still one of the clubs highest earners.
Tomas started his career with the Hammers by getting sent off on his debut and during his four years in England his disciplinary record has caught the eye.
With the club still looking to reduce their £12.3million wage bill, Repka looks set to be sacrificed.
Italian clubs Palermo and Brescia are both believed to be interested in signing Repka.
