Bayern make a steamroller start and win a corner, Mats Hummels heads it wide at the far post. Decent chance early on!

Nerves? You don't associate these titans of football with being edgy but there's a few ropey touches in the first minute or so. Cristiano Ronaldo's first touch is met with a chorus of jeers.

Away we go in both games!

You won't find a fan alive with a bad word to say about Gigi Buffon. You won't find many with a good word to say about Sergio Ramos.

I'm a big fan though. Win at all costs. The two captains embrace and shake hands with the ref who gives live texters typo nightmares - Turkey's Cuneyt Cakir.

Teams have overturned a first-leg deficit to go through 41 times in Champions League history, including Roma in this season's round of 16.

Only twice – Ajax's defeat of Panathinaikos in the 1995-96 semi-finals and Inter's victory against Bayern in the 2010-11 round of 16 – has a side progressed after a home first-leg loss.

Players in the tunnels at both grounds. LIght show in Turin, flags waving in Seville.

I love this time of year...

This is - remarkably - Real's 35th quarter final in the Champions League/European Cup, and a club record eighth in a row.

They have won 28 of them. GULP

Real Madrid boss Zinedine Zidane has refused to rule out managing Juventus in the future as the two clubs prepare to meet in the Champions League.

Zidane won two Serie A titles as a player at Juve between 1996-2001.

The Frenchman's long-term future at Real is unclear despite signing a new contract in September.

"Manager of Juventus one day? Never say never, but I'm happy where I am now," said Zidane.

If you're too young to remember Zinedine Zidane as a player at Juventus then I genuinely feel for you.

WHAT a player.

The number 21 represented Juve between 1996 and 2001, collecting two Serie A titles and playing in the 1997 and 1998 Champions League final defeats, the latter against Madrid.

He was half magician, half streetfighter. Half Zelda, half Ryu.

He was amazing - and he then moved to Real for an eye-watering (and brilliant) pricetag of 150bn lire.

That's 150,000,000,000. A comedy figure.

Briyan: Real Madrid are among favourites along with Man City and Bayern Munich. Since it's unbelievable that Madrid can win third in a row, I'll go with Bayern.

Maximilliano Allegri is an interesting character, somewhat maligned tactically, but for him at a club like Juventus it is about man management more than anything.

But also listening to your instincts. He knew at some point in the second leg against Tottenham there would be a period they would be vulnerable. So it was all about teaching his players to be calm until that moment.

He doesn’t go deep into tactics, but has the measure of a club like Juventus, he knows how important winning the Champions League is to them.

It is a fantastic achievement to reach the final twice in three years, but they lost both finals and it weighs heavy on them.

Again - ludicrous.

He pretty much defies time. The very aging process itself.

Cristiano Ronaldo of today is almost unrecognisable from the Ronaldo of 10 years ago. He's now pretty much a penalty-box targetman. But time isn't slowing down his Wayne Gretzky-esque scoring rate.

This season Ronaldo became the first player to score in all six group games in the Champions League, registering nine goals overall. He also struck in both legs of the last 16, meaning he has continued his record of finding the net in every game this season and is the competition's top scorer with 12 goals.

Ronaldo has hit the target in all five of his appearances against Juventus for Real Madrid – seven goals in all.

Ronaldo, who was rested against Las Palmas, has 23 goals in his last 13 games for club and country, including two in added time as Portugal beat Egypt 2-1 on 23 March. He has scored in eight consecutive appearances for Madrid.

23 in 13! That's a goal every 50 minutes (FIFTY).

We say it is a cliché. but Juventus do set up first and foremost to make sure they don’t lose, then break and score, which is why they have such a good defensive record.

Blaise Matuidi is not starting, Kwadwo Asamoah and Alex Sandro play and both are full backs.

They are the home team and Matuidi would normally play 99% of the time, so Allegri’s concern is to make sure his side are still in the tie. It is all about tonight, I think they would take a draw to be honest.

Can we have a moratorium on any 'Bale to Man Utd' stories this summer please?

At the weekend he scored twice but Gareth Bale is on the bench tonight. It may be that he was told he is needed later on in the game. If you only get one fantastic half out of him, use it in the second when the opposition players are a bit tired.

A player of his standard will think he can do better than sitting on the bench. But given Real Madrid are back-to-back Champions League winners, if he leaves the only way is down really.

Looks like a balmy evening at the Sanchez Pizjuan. Manchester United stank the place out in a 0-0 in their first leg in the last round and paid the price.

Bayern Munich will go for goals. Surely.

I don’t think Juventus will be afraid of Real Madrid. In the Champions League final last year Real Madrid went up a gear that Juventus frankly just didn’t have.

We have seen Madrid come back into form over the last few months since the turn of the year, but whether they can hit that peak like they did in that game, where they were unplayable for 20 minutes remains to be seen.

Over a two-legged tie, Juventus will still be confident they can edge out Real Madrid. But even with all of Real’s troubles at the start of the season, they again are coming good at just the right time, and this is all they have to play for.
