Fiorentina manager Paulo Sousa has urged his side to keep up their "positive momentum" and refused to dismiss talk of a title challenge.

The Viola currently sit top of the Serie A table after six games and Sousa admitted that while it will be difficult to maintain that position, his players are working hard to continue improving.

The 45-year-old told reporters: "It is difficult to prepare for games like this in just a few days as we have to move on immediately from our last game. It is important to stay focus.

"They have had more time to prepare for us but it is all about continuing our positive momentum. I don't think my players need any great motivation, being first in the table has given us encouragement and dreaming of the title doesn't hurt.

"We want to achieve perfection and we know that in certain games, huge effort will be needed to do that"

Fiorentina take on Atalanta at the Stadio Artemio Franchi on Sunday evening.
