Mario Santana is expecting Fiorentina to attack Rangers in the first leg of their Uefa Cup semi-final at Ibrox.
Fiorentina have failed to score in only one of their 12 Uefa Cup matches this season and won 2-0 away to PSV Eindhoven in the previous round.
Coach Cesare Prandelli has confirmed he will send his team out with a positive approach and Santana feels it would be unwise to change tactics for the Rangers game.
"Rangers will be a hard opponent and with experience of the Champions League, like PSV in the last round, but that will not be so decisive," the Argentinian attacker told skysports.com.
"Fiorentina do not arrive in Glasgow with a defensive mentality. That is not our usual system and it really will be an enormous failure to change in the semi-final.
"Really, the tie is 50-50, but that will change after the game in Glasgow. I do not consider Fiorentina to be inferior to Rangers if we look at our campaigns in the Uefa Cup."
Santana is predicting a hard-fought encounter against an injury-hit Rangers side and is hoping Fiorentina's technical ability will see them through.
He added: "I have seen some of Rangers' matches in Europe this season and I expect a lot of work in these two games.
"Against these clubs with a British style, it is necessary to play to your top level and be assured in front of goal.
"The defenders are very strong and perhaps the key is to profit from our technical play to open up the defence."
