The Blackburn boss also praised debutant striker and Rovers matchwinner Jon Stead.
"I thought Brad Friedel was outstanding. He was the best keeper in the Premier League last season and he showed his class here," Souness said after the 1-0 win.
"Brad Friedel kept us in the game. In fact he won us the game with two brilliant saves.
"I was also pleased with Jonathan Stead. He took his chance really well."
