FC Barcelona let go of a player who caused doubts. His performance at the blaugrana club was always marked by inconsistency, injuries, and a lack of constancy. Many thought his departure wouldn't be a great loss, but two years later, his breakout has shown that Xavi Hernández was right to defend him.
Now, Hansi Flick and Barça could suffer from it in the Champions League if he crosses their path.

An Unexpected Problem for Flick
Barça has improved with Flick, but they still have problems in defense. Despite having players like Ronald Araújo, Jules Koundé, and Alejandro Balde, the team has shown certain weaknesses against opponents with fast and unbalancing strikers.
In several matches this season, the team has struggled to stop explosive players, which has raised doubts about a possible clash in the Champions League.
The problem is that, if fate wills it, Barça could face their great nightmare in the top European competition. The player they let go is experiencing the best moment of his career and could become a major headache for Flick.

His Change in Performance Has Been Spectacular
When he left Barça, few thought he could become a global star. His first season at his new club was modest, with ups and downs that made it seem he would remain an inconsistent player.
However, in 2025 everything has changed. He is now the top scorer of the year in Europe.
In his new team, he has found a perfect environment. His speed, dribbling, and explosiveness have been maximized. He is now the great star of his team, something he never quite achieved at Barça.

Xavi Hernández Always Trusted Him
When the player left Barça, Xavi Hernández insisted that he had special talent. At the time, many didn't believe him. It was thought that his inconsistency and lack of constancy wouldn't allow him to reach the elite.
But today, that same footballer who left through the back door has become one of the biggest threats in Europe. Xavi wasn't wrong, and now Flick and Barça could pay dearly for it.
If the blaugrana team crosses paths with his new club in the Champions League, Hansi Flick will have to devise a perfect plan to stop him.

The Return of Barça's Big Problem
This player, who never managed to be the offensive leader expected at Camp Nou, is now one of the best in the world. His departure was low-profile, but his evolution has been impressive. He is now at his best, with total freedom in his new team's playing system and surrounded by players who enhance his qualities.

At PSG, the French winger has found his best version. His speed, dribbling, and determination have made him a nightmare for any defense.
If Barça faces PSG in the Champions League, Flick will have to find a way to stop a footballer he knows very well. But who is now more dangerous than ever. Dembélé has gone from being a problem at Barça to becoming Barça's big problem.
