The 20-year-old helped the Catalans to the win alongside Xavi and Andres Iniesta, and speaking to Canal Plus, gave his thoughts on the victory.
"The [most] important thing is to get the [three] points, no matter what the outcome is," he said.
"It is always said that when people return from international duty, it is a little more difficult for clubs to play their forthcoming games, but we could deal with it in the first half and we have done well."
He also gave an insight towards Gerard Pique's hamstring injury.
"Pique has played several matches for Spain and is exhausted, but he will recover soon and will be with us once more," he assured.
Barcelona are comfortably atop the La Liga standings after their victory.
