The 19-year-old Germany international has already scored four goals in three games this season, including a double in Bayern’s Bundesliga opening 6-1 win at Eintracht Frankfurt.
“Jamal is an extremely humble player who always wants to learn,” Nagelsmann said.
“He doesn’t put himself first, but rather the team - and that’s why he’s so valuable to our club.
“It’s always about looking ahead and confirming these performances. I hope he’ll have many other performances like today and score goals.”
Nagelsmann was delighted with the win which maintains Bayern’s perfect start to the season, having won the Super Cup 5-3 over RB Leipzig.
“We’ve had three good opponents at the start of the season and we’ve been able to beat all three, so we are very happy with that,” he said.
On Sunday’s performance, he added: “In the second half, it was all about control for us. We wanted to have more possession and direct the game.
“We wanted to show more energy in the first half to be honest, but Wolfsburg stood up well physically.
“We could have scored a third towards the end, there were also many times we were caught out offside. It’s a deserved win, we had 24 shots on goal.”
