Olmo praised Diaz, calling him a "world-class player" amidst rumors that the Colombian winger might join Barcelona this summer. He refused to comment further on their private conversation, saying he didn't know Diaz before and only had good things to say about him.

Olmo also spoke about Nico Williams, a winger from Athletic Bilbao, who Barcelona is reportedly targeting this summer. Both Diaz and Williams could join Barcelona in the coming months, and Olmo expressed his desire to play with the best players.

Olmo described Williams as a "very top player" but emphasized the need to respect his current team. He believes that the best players should play for Barcelona and expressed his admiration for Williams's skills on both his club and national team.

Olmo's comments come as Liverpool manager Arne Slot is considering keeping Diaz for the new season. However, if Barcelona makes a bid for Diaz, it's possible that Slot may reconsider, especially since Diaz has expressed his openness to a move if it's the right time.
