Roma forward Adem Ljajic has been declared doubtful for this weekend's clash with Inter Milan as he continues to struggle with injury.

Ljajic has largely been restricted to substitute appearances in recent weeks by a sciatic nerve problem, forcing Roma boss Rudi Garcia to monitor the youngster closely.

The Serbian starlet took no part in training today and is thought to be unlikely to feature at the San Siro on Saturday night.

The 22-year-old has helped Roma make their best ever start to a Serie A campaign after making a summer switch from Fiorentina, scoring three goals in four appearances.

Garcia's table-toppers won their sixth successive game last weekend, with Ljajic coming off the bench to net in a 5-0 win over Bologna.
