Valencia coach Ruben Baraja says they're staying patient with Roman Yaremchuk.
Baraja is confident the striker will make an impact with Los Che.
He said: “Roman arrived on the last day of the transfer window, almost without training in preseason and it is not easy for him to adapt.
"He also went away with the national team and now he is starting to train with us much more often. We hope for an improvement. The other day he played some good minutes at Mestalla.
"The feeling is that he is going to do better, he is going to grow and he is going to contribute things for us. Hugo Duro is scoring goals and I have to choose. Roman is different from Hugo and he can offer us things, just like Alberto. Everything that means competition is going to make us grow as a team."
