Spanish media reports indicate that FC Barcelona is no longer as optimistic about finalizing the transfer deal for Nico Williams as they were in previous days, due to difficulties related to registering the player.

The Spanish newspaper 'Marca' reported that although Barcelona is willing to pay the buyout clause in the player's contract with Athletic Bilbao, the main issue lies in finding a legal framework that allows for his official registration in the team's roster for the upcoming season.

Sources indicated that Barcelona and Nico are seeking alternative solutions, but so far no agreement or clear exit has been reached, putting the deal at risk of failure.

The source added that there are voices within Barcelona beginning to doubt the possibility of completing the deal this summer.

The Spanish star has a buyout clause in his contract worth 58 million euros, and the deal could reach 62 million euros.
