Totti has returned sooner than expected from a thigh strain.
“I feel good and think I’m nearly 100 per cent fit,” he told Roma Channel.
“Today I worked with the squad and had no problems at all, so I think I am fully at the disposal of the Coach.”
He added: “I would like to be at the top of my form already, because every game – starting from Sunday – is important now.
“I am not there yet, but I’m improving day by day and hope to be in top shape against Arsenal.”
