At the 2023 edition in Planica, Slovenia, the Swedish team picked up four gold medals, three silvers and five bronzes to finish second in the medal table.
12 medals in all was a new record total for Sweden, though that was still some way behind Norway's 27.
One of the challenges now for Bystrom, as the teams converge on the Granasen Ski Centre, is to manage heightened expectations of going better again this time around.
Speaking to Swedish news agency, TT, Bystrom gave an honest assessment when asked if Sweden could go beyond 12 medals.
"We have a completely different opposition now, one must be honest about that. So we have no such expectations," said Bystrom, who has been in charge of the Swedish team since 2020.
However, he was still optimistic that his team could have a successful world championships, adding, "But on the other hand, we know that in the best of worlds, we have a medal chance every day, really."
Sweden have sent a 15-strong team (eight women and seven men) to Trondheim for the championships which run until March 9th, with medal events taking place on 10 different days across various disciplines in cross-country skiing, nordic combined, ski jumping and para cross-country skiing.
All of Sweden's 12 medals in 2023 were won in cross-country skiing, and 11 were won by their female athletes, but Bystrom hinted that this time around, the podium places might be more evenly split throughout the team.
"We are also in a different position on the men's side where William Poromaa and Edvin Anger have won this year. So we have more opportunities there now than before, even though the opposition is extremely tough."
Along with Poromaa, who took bronze in the 50km classical mass start in Slovenia, all five female skiers who took home a prize in 2023 are back for the 2025 championships, including gold medalists Jonna Sundling, Emma Ribom and Ebba Andersson.
