The Nerazzurri had been hoping to clinch their third straight Scudetto last weekend by beating AC Milan at the San Siro but the Rossoneri prevailed 2-1 to keep the title race alive.

It was the third Serie A defeat of the season for Inter, who lead Roma by three points with two games remaining but holding the head to head edge with the Giallorossi.

"We face a final against Siena," said coach Roberto Mancini.

"We just need to take three points from our next two games but I'm convinced that we will seal the title this weekend."

Despite Siena beating Juventus 1-0 last weekend, Roma expect no surprises come Sunday.

Except for a brief period at the start of the season when Roma led, Inter's dominance this season has been little contested until now.

Roma, who play host to Atalanta, shot themselves in the foot last month by being held to a 1-1 draw against Livorno, a result that saw Inter take a six-point lead.

"I believe Inter will win against Siena," said injured Giallorosso captain Francesco Totti.

"Despite a good season, we have so many regrets this campaign but I guess it's part of football."
