Barcelona coach Ernesto Valverde defended Antoine Griezmann after their stalemate with Slavia Prague.
Griezmann drew another blank as this Champions League tie ended 0-0.
But Valverde said, "He is adapting to what our team is. It's not simple.
"When you come from outside, joining the team is not easy. He has virtues that are good for us. From a defensive point of view, he helps us a lot and he can still bring us more things."
