Three crucial battles that might decide El Clasico.

On Saturday night, Real Madrid and Barcelona will face off at the Bernabeu in La Liga's first Clasico of the 2024/25 season.

Three points separate the two passionate rivals at the top of the Spanish standings, with Barcelona having a tiny advantage over Madrid heading into this match.

A Catalan victory would be a big statement as Hansi Flick attempts to win only his club's second La Liga title since 2019, with the chance to open up a six-point advantage over Los Blancos.

However, if Madrid wins the most points, they will move into first place, level on points with Barcelona but ahead on head-to-head tiebreakers.

This is perhaps the biggest single game in world football, and viewers from all over the world will be glued to their televisions when it kicks off in the Spanish capital.

Vinicius Junior versus Jules Kounde.

While he split a role with Jude Bellingham last season, Vinicius Junior is now Madrid's key man. The Brazilian has scored or assisted in nine of the club's 10 La Liga games this season, and he made his Champions League debut on Tuesday, destroying Borussia Dortmund with a hat trick.

Vinicius returned to his more normal left wing role against Dortmund, after playing in a front two with Kylian Mbappe in the previous four home and away games. However, Rodrygo's involvement forced the swap back to the left side, and he has since been ruled out due to injury, implying that Vinicius will resume his center position.

He will be free to go wherever he wants, but his heatmaps from recent games as a striker rather than a winger show him preferring gaps on the left. That will be an issue for Ballon d'Or hopeful Jules Kounde on Saturday night.

The Barcelona right-back played a fairly narrow position against Bayern Munich in the Champions League on Wednesday in an attempt to reduce space in the inner forward channels, where Vinicius is normally most threatening.

Raphinha versus Lucas Vazquez.

In midweek, another Brazilian winger scored three Champions League goals. Raphinha.

The former Leeds United player is thriving under Flick's supervision, despite speculation that he might be sacrificed for Euro 2024 hero Nico Williams over the summer.

Raphinha has been captaining the team in the absence of the squad's three other senior leaders, and he currently possesses football's most dangerous weapon: confidence.

Although he has four assists in his past two La Liga outings from a central position, it makes sense for him to play on the left wing at the Bernabeu, as he did against Bayern Munich. The reason for this is Madrid's right-back Lucas Vazquez.

The 33-year-old, who is also expected to wear Madrid's armband as the squad's most senior captain, has been repurposed as a full-back in recent seasons but is not a natural defender and may struggle against someone in such terrific form as Raphinha.

Jude Bellingham versus Pedri & Marc Casado.

Frenkie de Jong and Gavi have barely made a few replacement appearances between them due to long-term injuries, thus it seems excessive to put them back in the starting lineup for this match. De Jong learnt this the hard way, when 45 minutes in the previous Clasico in April set him back several months.

That implies Pedri and Marc Casado will most likely remain at the base of Barcelona's midfield. The pair, whose combined age (42) is only slightly higher than Luka Modric's (39), did a lot of hard work against Bayern, preventing the Bavarian giants from playing down the middle.

Despite being praised for their technical ability, they will need to use it against Jude Bellingham. He won two Classico's for Madrid last season. And, while it hasn't been a stellar start to 2024/25 for him by those lofty standards, the Englishman remains capable of altering a game in an instant.

Squeezing the space in locations where Bellingham prefers to function may frustrate him.
