Barcelona coach Ernesto Valverde gave starts to Philippe Coutinho and Ousmane Dembele for their 6-1 rout of Girona.
Afterwards, Valverde made clear he will be patient with the duo.
"Both are players who we have extremely high hopes for," he intimated.
"Coutinho plays well in the midfield and scored a fantastic shot.
"Dembele has more depth, he's raw and is still very young.
"His injuries meant he skipped an adaptation period so he still needs to work."
