It looks and sounds fantastic. This is what football's all about.

Premier League teams - raise your game next year. You're missing out. And so are your fans.

"This game has the wow factor. We've got a fantastic view and every single Real Madrid fan has been given a white flag... not that they will be surrendering tonight. That's for sure."

The sides emerge from their segregated tunnel at the Bernabeu. Thousands of white scarves, as the familiar strains of the Champions League anthem rain down.

What a night in Madrid. So much at stake. Expect cards, fouls and drama aplenty.

Here we go then.

Time for us to enjoy our own perks of being at work and watch tonight's action. Can Real finally beat Atletico?

Jamie from Hereford: I work at a Go Kart Track, free karting whenever it's quiet. We also have a snooker table and table tennis table too.

"I think this will be another physical game. For me, Real Madrid look a little lightweight on paper. I'm going to go for Atletico to nick it tonight."

"I think Real Madrid, at home, are likely to score at least two goals. I don't see Atletico scoring more than one, so I think Real will go through."

A few cars have had a nightmare outside the Bernabeu. When shortcuts go wrong...

Ten minutes from kick-off in both of tonight's games.

First goal is massive tonight, even more than usual.

We saw last night a lesson in killing off a tie in 40 minutes from Bayern Munich. Nobody expects that from Real tonight, but an early goal for the visitors could well have this crowd up in arms.

Atletico goalkeeper Jan Oblak had a stormer in the first leg and he will probably need another one tonight.

For all of Real Madrid's injury problems they've still put out a fine side.

Francisco: We get unlimited fruit, toast and coffee machine every day.

Atletico Madrid have not lost in seven meetings with Real this season - and that is their best ever run of results in the derby. If they make it eight tonight, they'll be in the last four.

Diego Simeone has recently signed a new contract to extend his stay at Atletico - but will we ever see him manage in England? He'd be a bonkers but brilliant addition wouldn't he?

Jack from London: I think Atletico's team spirit will get them through the tie tonight. Real are less of a team, more a collection of talented individuals, and that could cost them.

I presume Steve is an upholsterer or furniture maker or something. Otherwise that would be weird.

Steve in Kidderminster: I made my own sofas at work.

Rob Hooper: I'd take our almost endless supply of jackets, baguettes and paninis anyday.

And I'm sure you do Rob.

It seems crazy doesn't it that Carlo Ancelotti could be under pressure for his job if Real go out tonight. When you manage the best, you have to be the best.

Pep Guardiola reacted well to being under (slight) pressure last night. Has Carlo got Real amped up?
