Barcelona coach Xavi hailed superkid Lamine Yamal after victory over Villarreal.
Barca won 4-3, with Yamal producing the assist for Gavi's opener.
"My expectations [for Yamal] are very high," Xavi told the press.
"He's a starter not because of the coach's whim. His decision-making is almost always correct. He's intelligent. He's exceptional.
"I'd like to see him play with the Spanish national team. He hasn't told me anything about his plans. I hope he stays at Barcelona for many years.
"He has the potential to make a mark. But with patience. I don't think there will be management issues. He's delighted and happy. He's humble, works hard, loves football... I see him ready to play. His age surprises me: just turned 16."
