Barcelona are welcoming a really tough opponent to the Camp Nou this weekend as Sevilla are making their trip to Catalonia. With such a stern test ahead of them, their Brazilian star in the middle of the park will have to be at his best.

On the chalkboard

By all accounts, Blaugrana's start to the 2019/20 La Liga season definitely could've been better.

But their performances at home have never been under question. Just this campaign alone, Barcelona have won all of their home clashes across all competitions, scoring a total of 14 goals in just four games.

Even by their high goal-scoring standards, that is a sublime figure and something Sevilla should be taking into account when preparing for the clash.

Still, the Andalusians are no slouch themselves. Currently, they are just one spot below the Catalans in the standings and a good result at the Camp Nou might see them jump over their Sunday evening opposition.

For that reason, Barcelona will need Arthur Melo to maintain his great form and outperform Joan Jordan on the other side of the pitch.

A midfield clash

The 23-year-old Brazilian midfielder has really taken the stage by storm this season, and the fans are loving every second of it.

Arthur was even likened to the legendary Xavi Hernandez by some of them and if these early signs and brilliant performances are any indication, he could really go far in his Barcelona career.

So far, he scored two goals and assisted one in the 2019/20 La Liga campaign but he also averaged 1.3 key passes, one shot and 3.3 dribbles per game in the domestic competition. But his Sunday counterpart, Jordan, is not really far behind either.

The 25-year-old Sevilla ace also tallied two goals and one assist in La Liga, accompanying that with 1.6 key passes, 1.1 shots and 1.9 dribbles per game.

By all accounts, that looks like a battle between two equally-matched players with similar strengths and quality.

Barcelona will, however, be hoping Arthur continues his great run of form and outperforms Jordan in front of the roaring Catalan crowd.

It won't be easy but that triumph just might be key for Blaugrana.
