Former coach Peter Kisfaludy worked with Bergvall in the youth team of Brommapojkarna, where he first saw Bergvall's exceptional skills at a young age.
"I was impressed by him from the very start," Kisfaludy said. "I worked with him from the time he was nine until he was 14, and I thought he was special right after our first training session together."
Kisfaludy has a reputation for identifying and developing talented young players in Brommapojkarna.
"I've worked with many skilled players over the years, including Viktor Gyökeres, Dejan Kulusevski, John Guidetti, and Ludwig Augustinsson," he said.
"But Lucas Bergvall stands out from the rest. He has a natural talent and always seems to know what's going on in the game."
