Zdenek Zeman says that Roma's winning streak has been down to simple changes and the team having more hunger.
The Giallorossi have won their last five games to climb up to fifth place in the Serie A table.
"The team is playing well and that is simply because we keep our tempo up for longer and make fewer mistakes. We also have the hunger and desire to take the game to our opponents," Zeman told a press conference.
The 65-year-old coach went on to say that his side will not be underestimating Chievo, their next opponents, but suggested that the condition of their pitch may be an issue.
"Chievo should certainly not be underestimated. We will also have to see the condition of the pitch as the weather will not help us pass the ball around to feet."
Zeman's Roma side are set to travel to Chievo, with kick-off scheduled for 15:00CET on Sunday.
