Guerin was promoted to the role of Coach after Rossi was fired on Wednesday night for physically attacking Adem Ljajic.
“I absolutely did not steer Fiorentina to safety,” insisted Guerini. “There was work done by two Coaches before me, above all by Rossi recently, and we had already seen improvements in our away form.
“We have often done well outside Florence, while at home there are some psychological problems of the pressure caused by our fans. At least we avoided the humiliation of challenging for safety on the final day of the season.
“I have to compliment the players, as they held out though many were in disastrous physical condition. Many couldn’t play at all, others hadn’t played in a long time.”
