Swedish newspaper Aftonbladet reported that Bardghji, 20, was visibly unhappy at the squad's qualification celebrations at the team hotel after the Poland match, frustrated at having been left on the bench against Ukraine and out of the squad entirely for the Poland game.
Potter denied the episode was a factor.
"I don't know anything about that. It wasn't part of my thought process."
"I was busy celebrating the World Cup qualification, so I don't know what everyone else was doing."
Bardghji's absence from Sweden's 26-man squad for the North American tournament was one of the more surprising calls when Potter announced the group.
The youngster made 26 appearances for Barcelona across all competitions in his debut season at Camp Nou, contributing two goals and four assists, but regular minutes have been hard to come by with one of the world's finest in the same position ahead of him.
Potter acknowledged the omission was among the hardest decisions he had to make.
"It has been an incredibly tough decision. As a person and as a father, I know how tough it is to leave players out."
He added that the final squad was shaped by more than individual talent, with experience, group chemistry and squad balance all weighing on the selection process.
Bardghji responded on social media with a line from Psalm 23:4 — a passage widely associated with resilience through adversity.
Liverpool striker Alexander Isak, returning from injury, headlines the Sweden attack alongside Viktor Gyökeres. A summer move away from Barcelona, possibly on loan, is now widely expected for Bardghji as he seeks the playing time that could secure him a place in the international picture going forward.
