Roma boss Luciano Spalletti is preparing his side for Sunday's derby with Lazio, and believes it takes 'heart and passion to win'.
The sides face off at Stadio Olimpico on Sunday and are separated in the table by just one point.
"At this time we must prepare the team well," the Coach told Corriere dello Sport. "This means giving importance to details without neglecting anything.
“Of course, this is a special week and the team is highly charged.
“Anyone who focuses on Roma sees that they are doing well, but we have to give something extra for the derby because it takes heart and passion to win.
“Roma must always win and this is a derby to win."
