Alaves striker Lucas Perez is adamant Antoine Griezmann will prove his quality at Barcelona.

Alaves host Barca on Saturday.

Perez declared, "Griezmann, Pedri or Ansu Fati? As a striker, the one with the most conditions is Griezmann, but the others are great players. Pedri is at a great level.

“Griezmann is one of the best players in the world but things are not going well for him.

"I think he's a great player, I think he could end up exploding at Barcelona."
