The tie may be evenly poised but Napoli boss Gennaro Gattuso still believes beating Barcelona will be a mighty challenge.

He said: "They are used to winning and I know that when you get used to winning you always want to do it. We have to climb Everest.

"In recent months I have heard many jokes, like 'Barcelona are not in shape', but if you go and watch them there are some players who put on a show."

Chelsea

Chelsea boss Frank Lampard, speaking to BT Sport: "The challenge in front of us is big. We'll see what we can do. The players have a choice about how they approach the game but it can only be one answer. They have to come here and believe they can turn the tie around.

"We have shown big moments throughout the season. It is a challenge for the players to show what they can do.

"We have to defend well and have confidence and be brave."

It's been fascinating to hear some of the stories from footballing legends on the Match of the Day podcast.

Manchester City progressed to the quarter-finals after they produced an impressive performance to beat Real Madrid 2-1 for a 4-2 aggregate win, although Real's cause was not helped by an usually poor performance in defence by Raphael Varane.

Meanwhile, Juventus failed to progress despite beating Lyon 2-1 on the night. A 1-0 win for the French side in the first leg meant they progressed on away goals.

Manchester City and Lyon will meet in the last eight a week today.

A good show of faith in the youth by Frank Lampard with three young English players in Chelsea's starting XI tonight - Callum Hudson-Odoi, Mason Mount and Reece James.

Wayne Ellis: As much of a legend as Pirlo was as a player, this is just a ridiculous move from Juventus.

Not since 2007 have Barcelona failed to progress to the quarter-finals of the Champions League, when they were knocked out by Liverpool.

Despite having the likes of Ronaldinho, Samuel Eto'o and Lionel Messi in their ranks, Barcelona found themselves frustrated as Liverpool went through on away goals after a 2-2 draw on aggregate.

Mark Gardner: Frank being Very Very OPTIMISTIC, but hey when you’re backs against the wall there’s only one way to go?. Come on you Blues.

Kevinaymla: As a city fan i hope they win, they'd be easier to beat than Bayern. but if Chelsea do manage it, my Chelsea mates will never shut up about it.

Eight years on and I still can't believe John Terry appeared in a full Chelsea kit, ​including boots, shin pads and sock tape, to collect the Champions League trophy in that 2012 final despite being suspended.

I've teased the comeback but, let's be honest, it is going to take a superhuman effort from Chelsea to turn this one around.

Only four times has a deficit of three or more goals been overturned, but no team has done so after losing the first leg at home.

Still, Chelsea boss Frank Lampard is not throwing the towel in.

"We have to believe we could have the opportunity to do something special." Lampard said.

"It is a huge task, no doubt, but games have turned to big degrees, some famous games and great games."

And Juventus have moved swiftly to name Maurizio Sarri's replacement, Andrea Pirlo!

He has signed a two-year contract until 30 June 2022.

An absolute legend, but think he can do a good job as a manager?

Maurizio Sarri paid the price for failing to reach the Champions League quarter-finals after he was sacked as Juventus boss earlier today.

Sarri guided Juventus to a ninth straight Serie A title but they were knocked out of the Champions League by Lyon last night.

Juve won 2-1 in Turin on Friday but the French side progressed on away goals.

Former Chelsea boss Sarri was appointed last year and although Juventus did win their domestic title, the football they played was pretty terrible at times.

Lionel Messi is free to walk away from the Nou Camp at the end of the season, but would he?

BBC Sport examines the relationship between Barcelona and Messi, who has put contract talks on hold.

Fintan: Chelsea aren't Liverpool and Bayern aren't Barca. No.

Sandie: I’ve been a Chelsea fan since 1966. But I’m also realistic! I don’t think they have much of a chance but that doesn’t stop me from hoping big time! Come on you Blues.

Do you think Chelsea stand any chance tonight? And who would you like to see win the Champions League and why?
