Fiorentina coach Cesare Prandelli admits Roma did them a favour after their 1-1 draw with Lecce.
With Roma's victory over AC Milan, Fiorentina will playoff for third place and automatic Champions League qualification with the Rossoneri this week.
"We are making a few calculations, but also relaxing and taking the time to celebrate this achievement of reaching the preliminary round," said Prandelli.
"From Tuesday onwards we will start the build-up and concentrate on the game with Milan. Sunday will have less pressure on us than today and the team will perform better.
"I am very happy for the results we have had this season. We had a few physical problems today, but everyone wanted to be there and contribute."
