Is Nico Williams getting nervous? Winger wants registration guarantee from Barcelona as he hopes to avoid Dani Olmo situation after €58m release clause is triggered

According to Marca, Williams has reportedly informed Athletic Club through his agent that he wants to don the Barcelona shirt from next season and is close to signing a six-year contract. However, the player reportedly wants a guarantee from Barca that they will be able to register him with La Liga after triggering his release clause.

The drama around Dani Olmo's transfer to Barcelona last season is still fresh in the fans and players' minds. The Spanish midfielder was eventually registered in August after the season had started, due to Andrea Christensen being ruled out with an injury. The player remained registered until December 31st, after which he once again went out of Barca's book. After a legal battle with the Spanish football council, Olmo was registered back into the team.

Barca president Joan Laporta remains confident of triggering the release clause and signing Williams this summer, while complying with all the demands of La Liga and Financial Fair Play. However, La Liga president Javier Tebas has warned they are in no position to register him.

Hansi Flick's side will be back in training in July and will then jet out to Asia for a pre-season tour.
