Tottenham winger Aaron Lennon suffered a fresh injury setback in their Europa League victory over Shamrock Rovers.

The England winger was substituted at half-time with a groin problem that makes him doubtful for the London derby against Arsenal on Sunday.

"Aaron's okay. He said his groin was a bit stiff and he didn't feel he could play on but I don't think it's too bad. We'll see when he comes in the morning," said Spurs boss Harry Redknapp.
