As linemates the past two seasons, Gaudreau and Monahan have combined for 112 goals and 267 points.
Gaudreau and Monahan will be teammates with Team North America in the World Cup of Hockey 2016, which will be played at Air Canada Centre in Toronto from Sept. 17-Oct. 1. Gaudreau will play even if he doesn't have an NHL contract.
"It takes time," Monahan said. "I'm positive he's going to be here for Oct. 12 [regular-season opener at the Edmonton Oilers] and be playing for the Calgary Flames. I'm not worried about it. Brad is doing his work on that part. I'm just looking forward to getting off to the World Cup and playing with him there, and continue that chemistry into the season."
Monahan said he doesn't have any inside information on negotiations with Gaudreau. Their offseason conversations have not included contract discussions.
"To be honest, we don't really talk about it," Monahan said. "We both have different agents and we're just friends and teammates. That's the business side of it. We didn't get into too much detail about it. We just talk about regular things we'd normally talk about. I'm just happy my deal's done. Hopefully, Johnny can get done soon and we'll get back on the ice together.
"He's an important piece of the team. He's a great player. He's one of my best friends. I'm sure he's going to get done soon. I'm looking forward to that."
