Chelsea hold a 1-0 lead from the first leg at Stamford Bridge a fortnight ago, but Del Piero still believes that can be overturned at the Stadio Olimpico with a repeat of their performance in London and a bit of luck.

"We played well there a fortnight ago," he said. "Chelsea played quite a good game and won, we played a very good game but lost.

"Hopefully we can turn that around tomorrow night.

"We have been particularly looking forward to this game and tomorrow we will have to play the perfect game."

An away goal in London would have given the Bianconeri more hope of going through, but Del Piero refuses to see it as a lost cause.

"We have got to concede as little room as possible and take our chances intelligently," he added.

"I hope that tomorrow night the whole of Juventus is on top of its game, not just me, and then we can go through.

"The result may be negative at the moment, but it is not terrible. Certainly, we cannot rely only on technical and tactical aspects tomorrow; we need to play with our heart, the desire to win, enthusiasm and passion."

Coach Claudio Ranieri is asking for even more than that.

"Juventus has such a history in Italian and European football and all of the players who arrive here realise what it means to where this shirt," he said.

"It may be a heavy responsibility to wear it, but we have got to give it the maximum.

"When we reach the maximum, we then have to go beyond that."

Two years ago, Juventus were playing in Serie B after an enforced relegation from the top flight of Italian football for the first time in their history.

They have worked hard to get back into a position to play matches such as this one and Ranieri will be asking for one more effort to keep the dream of renewed European success alive.

"Tomorrow night we play on the international stage," he said. "We have done a lot to get here and we want to stay here.

"We are playing on three stages and tomorrow's is beautiful and stimulating. It is the international one and we want to do well."

After losing Mohamed Sissoko to a fractured foot at the weekend, Ranieri received even worse news on Monday when he lost central defender Nicolas Legrottaglie to a recurrent knee injury.

"He still has the same problem with his knee," he explained. "He tried to train, but said he could still feel pain. He had never really fully recovered from it in the first place."

Former Aston Villa defender Olof Mellberg should take his place alongside Giorgio Chiellini at the heart of the Juve defence while Jonathan Zebina has been included in the squad after making his first appearance of the season in the Turin derby at the weekend.

Zdenek Grygera is also back after missing the derby while Del Piero and Amauri should start in attack, but Ranieri is not taking anything for granted.

He even refused to rule out naming David Trezeguet in an ambitious three-man attack.

"You can never be 100% certain about anything," he said.

"Usually I decide my team on the evening before the match, but sometimes I have to wait until the day of the game to see if there are any injuries.

"We will see. We have got to play all of our cards and I am convinced we will play a great game, whoever I field."
