Muller was one of the stars of this summer's World Cup as Joachim Low's side lifted the trophy in Brazil having overcome Lionel Messi's Argentina in the final.
Henry, now with the New York Red Bulls, is part of the Major League Soccer All-Star team set to face Bayern Munich this week, and he believes the forward does not get the recognition he deserves due to the presence of football's "freak" talents of Messi and Cristiano Ronaldo.
"Stepovers, tricks, that's not the game," Henry told a press conference. "The game is what Thomas Muller is doing. If I had a son right now, playing, I would say to him 'look at them, look at [Franck] Ribery, look at Muller.'
"What Ronaldo does, and Messi, they're just freaks. Don't try to copy those guys. You can copy from Ribery, you can copy from Thomas Muller.
"What he did at the World Cup, people don't talk about it. They don't talk about it, but they should talk about it. He plays the game the right way: he defends, he attacks, he controls the ball when he has to control it, he reverses when he has to reverse it. When he has to finish, he'll finish.
"He doesn't do stepovers, but when he has to perform, he performs. He does what the game asks him to do."
The MLS All-Stars face Bayern at Providence Park on Thursday at 03:00 CET.
