I think the Barcelona bus might be best to take take the back road to the Bernabeu. Here is the welcome afforded to the home team.

Our BBC accountants have got their calculators out and Real Madrid's line-up today costs £303m - to Barcelona's £223m.

Spanish football writer Graham Hunter on BBC Radio 5 live on Friday: "I think Luis Suarez fits in Barcelona's team brilliantly. He presses like Samuel Eto'o used to do at his best and it is something that Luis Enrique has asked the whole team to do.

"Secondly when you score as many goals as he does, you walk into any side. His threat will drag defenders away from Lionel Messi."

No room for Neymar in three of those four line-ups below.

Those are the kind of big calls you have to make when you are putting together a composite XI.

Tell us your composite El Clasico XI.

We've been asking you to name a best starting XI made up of current players from Barca and Real.

Ryan: Navas, Marcelo, Ramos, Pique, Carvajal, Kroos, Iniesta, James, Neymar, Ronaldo, Messi.

Jamie, Cheshunt: Ter Stergen, Carvajal, Alba, Ramos, Varane, Modric, Kroos, Iniesta, Suarez, Messi, Ronaldo.

It isn't only the fancy-dan forwards who are re-writing the record books either.

Barcelona's defence has yet to be breached in eight league games, a record for successive clean sheets at the start of a Spanish season for goalkeeper Claudio Bravo.

They came quite seriously unstuck against Paris St-Germain's quality in the Champions League last month though, losing 3-2.

Perhaps they are not quite watertight just yet...

Norris McWhirter, external would be furious.

Lionel Messi and Cristiano Ronaldo have been forcing continual revisions to the record books.

And there are more landmarks on the line today.

Messi's left-footed strike in Saturday's 3-0 victory over Eibar took him to the milestone of 250 career goals in La Liga, leaving the Barcelona man just one behind the record held by 1940s Athletic Bilbao star Telmo Zarra.

Ronaldo has scored 15 times in seven La Liga games this season. His streak has included three hat-tricks. Another this evening would be his 23rd in La Liga, one more than Zarra and Alfredo Di Stefano who he currently shares the record with.

Spanish football writer Graham Hunter on BBC Radio 5 live on Friday: "This has become the world's biggest game and a lot of that is just down to the sheer quality of the players. It has always had brilliant players, guys like Raul, Hristo Stoichkov, Maradona and Michael Laudrup, but it has never been quite like this."

Real Madrid: Casillas; Carvajal, Pepe, Ramos, Marcelo; Kroos, Modric, Isco; Rodriguez, Ronaldo; Benzema.

Barcelona: Bravo; Mathieu, Pique, Mascherano, Alves; Busquets, Xavi, Iniesta; Neymar, Messi, Suarez.

There it is then....

Barcelona have gone both barrels in the Bernabeu with a three-pronged attack consisting of Lionel Messi, Luis Suarez and Neymar.

Eye-wateringly awesome.

Real Madrid make two changes from the side that beat Liverpool at Anfield with Sergio Ramos and Dani Carvajal returning to the team in place of Raphael Varane and Alvaro Arbeloa.

There a couple of Catalan whispers on social media that Luis Suarez has been thrown straight into the Barcelona starting XI.

A big, bold move if true. We'll let you know when the truth lands...

Former Manchester United goalkeeper Peter Schmeichel
Football Focus

"There is no striker playing anywhere now who is as good as Luis Suarez was last year for Liverpool. He scored from everywhere. And the way he plays, you do not know where he is going. He does not have one single style as such. He has everything."

There's plenty of anticipation over Barcelona striker Luis Suarez's involvement in El Clasico. The Uruguayan is available again after his four-month ban for biting Italian defender Giorgio Chiellini at the 2014 World Cup and, during his time at Liverpool, he got better with each season.

Here's a little selection poser for you.

Boil two of the greatest sets of players ever assembled down to the best composite starting XI.

No naming a midfield consisting entirely of strikers either. We want balanced brilliance.

Get it right and you'll be close to an Earth XI to play Mars for the future of the planet.

We are 15 minutes away from the announcement of Carlo Ancelotti and Luis Enrique's starting XIs, but Barcelona have released their 18-man match-day squad., external

Luis Suarez, as promised by Enrique, is in. As is Sergio Busquets who missed the Champions League match against Ajax.

"It is a mouth-watering game. Ronaldo and Messi are, if anything, better than last season.

"It is so hard to call but I would go for Real to edge it this time.

"From what I've seen of them, the only thing that will stop them becoming the first team to win back-to-back Champions Leagues this season is their defensive problems because they can still have a bad day, but you can get to Barca at the back too.

"If you are a football fan, you just sit and watch this game and enjoy it. As a neutral it is great because I am not too bothered who wins but I just know it will be full of absolutely everything - quality, intensity and lots of incident. It is becoming an unmissable event."
