"It'll be emotional for sure, it always is when you get into those situations, it definitely won't be easy," Pietrangelo told NHL Network on Thursday. "Look, I met my wife here, she's from here, we got family here, there's so many things that attach us to this city. At the end of the day, I still have a job to do when I do come and play. It's gonna be emotional for a long time, not just the first time I play. It's gonna be emotional every time I come here."
The 30-year-old has spent his entire NHL career with the Blues since they drafted him fourth overall in 2008. He became team captain in 2016 and helped guide the club to a Stanley Cup victory in 2019.
He signed a seven-year, $61.6-million contract with the Golden Knights as a free agent this offseason.
Pietrangelo knows, however, that once the puck drops, it'll be all business against his former team.
"I grew up here, I grew up as a player, I grew up as a person. I still got family and friends here, I'm sure they're going to be at the games, too," Pietrangelo said. "So all that comes into play but I'm sure once the game gets going, these guys don't let me get off easy and it'll be a wakeup call for me."
He appeared in 758 games with the Blues, racking up 109 goals and 341 assists. Since his rookie season in 2010, Pietrangelo ranks seventh among all defensemen in points.
