Roma captain Francesco Totti is in danger of missing their Champions League return-leg tie against Arsenal.

Totti looks likely to miss Saturday's encounter with Udinese as his knee injury problems persist.

"It's hard to talk in terms of time," fitness Coach Vito Scala admitted on Centro Suono Sport.

"He is still feeling some pain. The tests gave a negative result, He has inflammation on his knee and that's why he is suffering."
