Former Roma coach Fabio Capello is backing his old club to win Friday's derby against Lazio.

Roma picked up a 2-2 draw against Inter on Sunday, while Lazio beat Parma 2-0 at the Stadio Ennio Tardini.

“Roma seem more prepared, but derby clashes are always special," Capello told Radio Rai.

“I like how Roma play, I've been saying it for long time. Against Inter, however, they switched off for 20-25 minutes and then played very well again in the final 20 minutes.

"In the Olimpico match both clubs had ups and downs, but a great team must not make mistakes".

“Lazio did very well too, but they are missing a few key players and that could make the difference."
