Zidane warns Napoli there will be no let up from Real Madrid

Naples - Zinedine Zidane has warned Napoli there will be no let up for 90 minutes when Real Madrid looks to seal its seventh successive qualification for the Champions League quarter-finals.

After a 3-1 defeat at the Santiago Bernabeu last month, Napoli hosts the 11-time European champion Tuesday dreaming of causing a major upset and securing its first berth in the last eight of Europe's premier club competition.

Zidane has fond memories of the San Paolo stadium having played against Napoli during a five-year spell with Juventus.

But although he expects a "difficult" game, the former World Cup winner said Real expects one result only.

"It will be a difficult game, the same as it always is in the Champions League," Zidane told a packed conference in Naples on Monday.

"It's never easy here. I've played here in the past. The fans always get behind the team, which is really great, but it also spurs us on as well.

"We're more than ready. We've come here to win, not to try and manage the game. We'll suffer, but we're motivated."

Credited with playing the most attractive football in Italy, Napoli made a bright start to the first leg thanks to Lorenzo Insigne's audacious long-range strike in the opening minutes.

But goals by Karim Benzema, Toni Kroos, and Brazilian midfielder Casemiro offered a stark reminder of Real's European pedigree.

Zidane's men are firmly in control and if Napoli is to go through on away goals, the Serie A side will have to do what no team has managed since Wolfsburg beat Real Madrid in a quarter-final first leg nearly a year and 46 games ago - keep a clean sheet against the reigning Champions League winners.

A fast start with an early goal - and an all-round tight defensive display - would ideally be required from the host.

But Zidane appears to have covered all the bases.

"Obviously they will play with a lot of intensity at the start of the game. But Napoli are a team that knows how to play in different ways," added the Frenchman.

"They're strong on the counter-attack and they use the flanks well. Tomorrow it's crucial we start well. But we also have to have intensity for 90 minutes.

"I want us to leave everything out on the pitch and play good football, but also use our heads."
