Galchenyuk will center a line with Desharnais and Andrew Shaw on his wings against the Flyers on Thursday (7 p.m. ET; CSN-PH, SNE, RDS, NHL.TV).
"I think we're all different players," Galchenyuk said. "[Desharnais] is a playmaker, I can make plays but I'm more of a shooter and [Shaw] you always need guys like that on your line, works hard, competes, does the little things right. I'm excited to see what we're going to bring [Thursday]."
The decision to use Galchenyuk on what amounts to Montreal's second line attests to the play of Phillip Danault on the first line with Max Pacioretty and Alexander Radulov. Danault, who began the season the on the fourth line, is easily the biggest beneficiary of the Canadiens' injury problems.
Therrien evoked the Pittsburgh Penguins and their ability to play someone like Phil Kessel on the third line when explaining the luxury of being able to play Galchenyuk on the second line.
"We're looking for balance on every line, and you can't have a better example than the Stanley Cup winner; they've got Kessel on the third line," Therrien said. "They're really well-balanced and they're tough to play against, honestly, because of their balance. I wish I was able to do that. I think we're more a threat when we balance our lines instead of putting all those guys together."
