Real Madrid are gearing up for their biggest test of the 2019/20 season so far as they travel to Parc des Princes to face PSG in the opening match of their Champions League group.

And looking at the squads, it will be crucial for the Galacticos to shut down the French side's wingers.

On the chalkboard

Los Blancos have already conceded six goals in four games in La Liga and are yet to keep a clean sheet -their defensive prowess, or lack thereof, will be severely tested by the French giants.

Not conceding a goal for the first time this season will surely be a major objective for Zidane's men.

However, they will be without Sergio Ramos, who is suspended, and Marcelo, who became the newest name on the injury pile, for this clash.

With that in mind, a huge part of the defensive responsibility might fall on Daniel Carvajal's shoulders, and he will have to win his battle against Angel Di Maria of all people.

The Argentine is usually deployed as a right-winger for Paris Saint-Germain but seeing how they've been riddled with injuries and suspensions - Kylian Mbappe and Edinson Cavani are both ruled out - the only real natural left-winger left in the squad is Eric Maxim Choupo-Moting.

Given the importance of this game, then, Tuchel might reshuffle the deck just a bit and put Di Maria on the left flank instead of Choupo-Moting - best known, perhaps, for a spell at Stoke City - and then shift Pablo Sarabia to the right.

With such a setup, Di Maria would get face to face with Carvajal.

Stopping the bleeding

Carvajal has so far featured in three games for Real Madrid this campaign and he has performed well.

The 27-year-old defender has tallied 1.7 tackles, 1.3 interceptions and 1.5 fouls so far in La Liga. This stacks up against Di Maria's 1.6 shots, 2.4 key passes and 3.8 dribbles per game.

Still, despite his numbers maybe being somewhat lower than his opponent's, he looks ready to face the challenge and even emerge victorious from it.

During the international break, Carvajal was shining for Spain and also laid on an assist in Real Madrid's clash with Levante on the weekend, suggesting he's definitely starting to peak.

Seeing how his dancing partner is looking to be the experienced Argentine winger - formerly of Real - this will definitely be a tall task.

Thus far this season, Di Maria has three goals and one assist to his name in all competitions.

He will be out for more this week; it is up to Carvajal to stop him.
