Fati became Barca's youngest ever league goalscorer against Osasuna last month and marked his full Camp Nou debut on Saturday with a goal and an assist in the first seven minutes of the 5-2 thrashing of Valencia.
"I've not spoken with him, save for tactical matters," Valverde admitted. "I don't like the history of giving advice. Of course I will talk with him, but you have to give him some breathing space.
"What he is doing is exceptional. If he plays, it's not so he can break a record, but because of the needs of the team. We love him."
