Viktor Gyokeres is adapting to unfamiliar surroundings at Arsenal but he shares common ground with two of his new neighbours in north London. Like Tottenham's Dejan Kulusevski and Lucas Bergvall, he is a product of IF Brommapojkarna.
"Compare that to us at the time, we were having to fight for every game, to get the points in order to say in the division, so the conditions were not ideal for young players to really shine."
Gyokeres, who came later to Brommapojkarna's academy than Bergvall, aged 14, from another small club in Stockholm called IFK Aspudden-Tellus, was a different case given he was sold directly to a European team in Brighton, moving to England aged 19 in 2018.
But the fee, for a player now valued at over £60m, was modest at under £1m, in part because Gyokeres had not had the chance to prove himself in the top division with Brommapojkarna, who were playing in Sweden's third and second tiers at the time of his first-team emergence.
Fast forward to now and the benefit of being settled in Sweden's top-tier - Brommapojkarna rose from 14th in the season after their promotion to 10th last term and now sit ninth - can be seen in the club-record sale of 17-year-old midfielder Love Arrhov to Eintracht Frankfurt announced in May.
In the stable conditions of mid-table, Arrhov has been able to shine for Brommapojkarna, with Frankfurt not only agreeing to pay a fee which could reach eight-figure territory in euros if add-ons are met, but delay his arrival until January, ensuring his boyhood club retain an important player for the remainder of the Swedish season, which runs from March to November.
As well as Gyokeres, Kulusevski and Bergvall, the club count former Arsenal winger Anders Limpar, former Manchester City and Celta Vigo striker John Guidetti and ex-Juventus and Sampdoria midfielder Albin Ekdal among their most high-profile graduates.
But the percentages are of course vanishingly small, as they are for academy players in England and across Europe. The club do acknowledge the issues raised by Brenning.
"We now have a ceiling on how much parents can pay each year and the total can't go over that," says Berglund. "All our teams also have their own bank accounts, so if they want to go to extra tournaments or things like that, they need to find sponsors to pay.
"We never want a family to not be able to afford to be here. It's really important to us that everybody who wants to play football can play football. Of course, our players don't all come from rich families, so we also take the responsibility to sponsor specific players as well."
Brommapojkarna were regarded as trailblazers in youth development in Sweden but they are far from the only club now trying to generate profit through high-potential players as a priority.
Brenning likens the scramble to recruit the best talents in Stockholm to an "arm's race". In May, Alexander Andersson, a player poached from Brommapojkarna by Djurgardens, set a record as the youngest player to feature in the Allsvenskan at 15 years and 24 days old.
Some in the country believe the priority given to young talents over experienced players is taking a toll on the national team. Despite a growing number of clubs developing better, or at least more sellable, young players, Sweden have only qualified for one of the last four major tournaments.
For Brommapojkarna, though, the success stories will keep coming.
They have secured a record-breaking windfall through Arrhov but he is not the only member of their current side to have attracted interest, with 19-year-old striker Ezekiel Alladoh, scorer of four goals so far this season, also expected to fetch a big fee.
In Gyokeres and his new neighbours Kulusevski and Bergvall over in north London, they and the many thousands of other young players on Brommapojkarna's books have their inspiration.
