Roma striker Luca Toni admits they need Lazio to do them a favour this weekend.

Having lost to Sampdoria on the weekend, Roma have also surrendered the Serie A leadership to Inter Milan, who are Lazio's next opponents.

"It is a very difficult situation. We have to win all three games and hope that Inter will drop points," said Toni.

"I really hope Lazio will play a great game against Inter. Against the Nerazzurri they will need to give their best and I genuinely hope they will be willing to do so.

"But knowing that they are from the other 'side', I am not too confident."
