Roma coach Claudio Ranieri says the return to full fitness of Luca Toni can boost their title chances.

Ranieri admits Friday's shock defeat suffered by Inter Milan has opened the Scudetto door to Roma.

"We need Toni more than ever," confessed Ranieri. "He will be in the starting XI and is better than last week, when he had only two training sessions with us.

"You saw what an impact he made towards the end of the 0-0 with Milan, as he held the ball up and everyone poured into the box. We're in good shape physically, but have lost a bit of that sharpness that allowed us to have four incredible months."
