Valverde's double concern going into Athletic game

Barcelona coach Ernesto Valverde has not revealed who will fill in for the injured Sergio Busquets and the suspended Luis Suarez against Athletic Club on Sunday. 

However, he did concede it will be tough to find solutions which work, with the two players so vital to the Catalan side's success this season. 

"It's always a guarantee to have a player like Busquets against teams that press high," he said. "And the same with Luis, who's good at keeping center-backs pinned back." 

With regards to Busquets, Valverde said that "we have lost Sergio once before, to suspension, but we have players that can help, like [Ivan] Rakitic and others." 

He added: "But Busquets is fundamental for the team. He is the best player in the world in his position, so it's not easy to replace him." 

The same didn't happen when he was asked about Paco Alcacer, who could fill in for Suarez: "He's training well, he looks good. There's a lot of competition, some [players] play more, others play less.

"Paco is ready when called upon. These are the circumstances: I have to decide as the coach, that's football."
