At just 18 years of age, Vinicius Junior is already under the spotlight at Real Madrid in his first season at the Santiago Bernabeu.
In the 27 appearances the Brazilian has made since joining Los Blancos last summer, he's found the net just four times.
Vinicius' form in front of goal has sparked a debate in Spain that questions whether the impressive forward can be a goalscoring phenomenon later in his career.
"The composure to finish comes with maturity," Gines Melendez, coach of former Madrid forward Fernando Morientes, told MARCA.
"As a person and as a player. The coolness is another thing. You either have this or you don't. But everyone can work.
"Ask Morientes how hard we worked until he started to finish well!"
"I remember it well," said Morientes. "He had me shooting against a wall with both feet and the truth is I'm very thankful for it.
"It's like maths: the more you work, the better you get. Then it's true that it's all about being cold-blooded: I never had it like Ronaldo [Nazario]; this ability one against one.
"This is just natural, and he handled each one like he could. The Bernabeu, 100,000 people... But it's obvious that you improve by working. Vinicius has room for improvement."
"Of course, you train and you get better," said former Sevilla and Valencia striker Alvaro Negredo. "It's not all about placement, but intelligence and decision-making - that part Vinicius is lacking a bit.
"I don't want to say he's a bad player. He dares to take people on, and maybe he could be a bit quicker to calculate, but this can be improved. Bit by bit he will take better decisions because he's young."
"For me Vinicius isn't a centre-forward," said former Madrid and Real Betisstriker Alfonso Perez. "He has to take advantage of his pace, he doesn't have to be a goal scorer.
"He'll end up scoring goals, for sure, like all good wingers, but I don't think it has to be his main focus. When I was playing, I used to think too much about creating chances, but I told myself I had to change my mindset and think about goals.
"It's self-motivation, having ambition. Another thing is the ability he has. And, of course, you can work! Vicente Del Bosque had us working on finishing every Monday since we were young."
One of Perez's teammates under Del Bosque was Isma Urzaiz, who ended up scoring over 100 LaLiga Santander goals for Athletic Club.
"What Vinicius needs to improve most is the automatic movements of a striker," he said. "How you shape your body, expecting the pass, the most effective postures, this will give him efficiency."
"And with this comes confidence, one thing leads to another. Then comes the composure. At 18 years old it's difficult to have this composure, but Vinicius is an exciting player.
"I know great strikers that didn't have it at 18 and ended up scoring so many goals. Aritz Aduriz is a prime example: he scored goals at 19, but nothing like he could at 29."
"Goalscorers end up controlling their emotions," said Miguel Pardeza. "You don't think that you were born to score goals, but mental preparation helps a lot."
"Vinicius will improve many areas of his game," said former Madrid striker Sebastian Losada. "But it's difficult to pick up some traits you don't already have, no matter how much you work."
