from Austria’s Red Bull Salzburg, the club that signed him from the Philadelphia Union in late 2020. It was the second-highest transfer fee paid for an American in soccer history, trailing only the $70 million that Hershey’s Christian Pulisic commanded when England’s Chelsea bought him from Germany’s Borussia Dortmund in 2018.to the Union to bring Aaronson to Europe. The deal also gave Union a piece of a future sale, and further money based on performance incentives.
The Union won’t get any money from this latest move, because it was a loan. And they won’t get big pieces of future sales, but they will get small sums thanks to a FIFA rule that compensates the team that developed a player in his youth days.Zack Steffen came back home to Downingtown, a place that still means a lot to the USMNT goalkeeper
“Brenden’s commitment has made us very happy,” Union Berlin’s managing director Oliver Ruhnert said. “He is a type of player we don’t have who will be good for our attacking game. Despite his young age, he already has a lot of international experience and will complement our squad at a high level.” It will be the second time Aaronson plays for a Champions League club. He did so with Salzburg in the 2021-22 season, scoring two goals in a qualifying series win over Denmark’s Brøndby — a team that includedSalzburg then advanced from the group stage for the first time in its history. While it lost to German superpower Bayern Munich in the round of 16, Aaronson had an assist in both games of the matchup.
