The Giallorossi had a poor start to the season but have now won four of their past five matches.
“We are confident that we can beat anyone now, starting with [Adrian] Mutu and his Fiorentina this weekend,” Baptista told Sky Sport24.
“As well as this, fourth place in the championship is a goal that is well within our reach, and we are confident of achieving this.
“If we win the games we should win, then I think we will achieve our goal.”
