So it just had to be the teenage phenom who scored the decisive goal to clinch Barcelona's 28th Spanish league title.
And what a goal it was for the player who still wears dental braces and sports a new dyed-blond hairdo.
The 17-year-old struck the winner in Barcelona's 2-0 victory at crosstown rival Espanyol on Thursday when he slid past two defenders outside the area and whipped one of his now trademark left-footed curlers into the corner of the net.
It was a perfect culmination to Yamal's last 10 months.
After helping Spain win the European Championship last summer, Yamal excelled for Barcelona this campaign with his goals, dribbling and playmaking as he confirmed his status as the next big star of global soccer.
Along with Raphinha, Pedri and company, Barcelona were unstoppable in Spain.
"I always try my best and today I was lucky it went in," Yamal said. "I am very happy I could help the team and celebrate it."
Fermín López ensured the win in stoppage time after Espanyol was reduced to 10 men in the 80th when Leandro Cabrera received a direct red for hitting Yamal in the stomach while disputing a ball.
Barcelona won the title with two rounds remaining. They completed a domestic double with the Copa del Rey title - treble if you add the Spanish Super Cup - and reached the Champions League semi-finals in a fantastic first season for coach Hansi Flick.
Flick's team virtually ended Madrid's title defence when they beat their arch-rival 4-3 on Sunday, making it four of four clasico victories across all competitions this season.
Barcelona's players danced briefly on the field to celebrate while sprinklers doused them with water.
"You don't win a league every day and we have to enjoy this and give it the value it has," said Barcelona midfielder Pedri after completing his 200th game for his club at age 22.
Lionel Messi posted a message on Instagram sending "Congratulations" to his old team. Real Madrid also congratulated their fierce rival on X, while thousands of Barcelona fans gathered to celebrate in downtown Barcelona.
Yamal credited his coach for inspiring a core of players who had won nothing last season under Xavi Hernández.
"We are thankful for what Xavi gave us, but it is true that coach (Flick) has given us a new life," Yamal said.
Looking back on his arrival in the summer, Flick said he had instilled a "positive" attitude in his team and they had adapted well to his style of play that requires a high defensive line and all-in pressing.
"Barcelona has to win titles and three titles is really great," Flick said. "I suffered a bit after the game in Milan, but after winning three titles I am very happy and the club is too."
On Yamal's goal, Pedri said: "He scored two goals like that today in practice. We are fortunate to have him on our side."
