Even though his side hold a 2-0 lead from the first leg, Prandelli claims he will not change his style of play.

He is is expected to play 4-3-3 with Mario Santana, Pablo Osvaldo and Christian Vieri up front.

It is a bold statement by Prandelli with a place in the quarter-finals at stake.

He said: "It is always hard to play an English team in their own stadium.

"The supporters will be fired up and we know it will be a difficult game.

"But we are well prepared and will not change our tactics, even though we are two goals ahead.

"We do not intend to defend that lead but try to score more goals."

Fiorentina are chasing a Champions League place despite the setback of losing to Siena at the weekend.

And Prandelli was pleased with the way they played in the first leg against a team unbeaten in the nine Premier League games before the match.

He said: "It was not a surprise to get such a great result as we have been playing well.

"But we know it will be much different when we face Everton tomorrow in front of their own fans.

"They have three or four top quality players and have a good record themselves this season.

"I am expecting a physical game with a lot of long balls but my team is ready for the challenge."

Asked whether he would prefer to win the UEFA Cup, rather than claim a place in the Champions League, Prandelli added: "I am not thinking that far ahead, only about the next game."

David Moyes, meanwhile, admits his mind has been in turmoil because of the Fiorentina factor.

The Everton manager was left with a sense of disbelief as his high-flying side went down 2-0 in the first leg last Thursday.

While Moyes saw his side recover superbly to win on Sunday at Sunderland and stretch their unbeaten league run to nine games, Fiorentina dominate his thoughts.

He said: "I have never stopped thinking about possible scenarios since that first-leg game.

"I did not sleep after the match but hopefully we can put into practice something that makes us play better against them tomorrow.

"It was a bit strange over there and a bit flat as we did not play as well as we can do. We have done well enough in the UEFA Cup to get to this stage, apart from one game in Italy.

"It means we now have a big task but one that can be overcome."
