Wilder saw Berge when he played the full 90 minutes against Sweden away in a Euro 2020 qualifier.
Sheffield United broke the clubs transfer record for the fifth time since they got promoted to the Premier League again.
Berge signed from Genk for £22million.
He got his debut against Crystal Palace.
“Sander can be pleased with his performance, he has fitted in fantastically well and certainly there is more to come,” Wilder said after the game.
