Guhle put Montreal ahead 1-0 at 15:53 of the first period, taking a pass through the slot from Mike Matheson for a wrist shot alone at the backdoor.
Eller tied it 1-1 at 4:05 of the second period with a wrist shot from the slot after Valtteri Puustinen’s shot went off Matheson’s skate in front.
“The most important thing in my mind was getting the two points,” Eller said. “That’s what I’m the most happy about. These points were crucial for us going into this break with a little bit better feeling getting three out of four in the last two (games). It wasn’t our best game. We were fighting it a little bit.
“We’re never quitting. We’re never giving up. We find a way, even when we’re not playing at our best, to come back into games and get points. That’s huge. Just happy, most of all, about the two points.”
Slafkovsky gave the Canadiens a 2-1 lead on a power play at 12:23 when his wrist shot deflected in off Penguins defenseman Ryan Graves in the crease.
"That's what I've been looking for my whole life,” Slafkovsky said. “I want to be the difference maker. I want to be the man. I'm working myself up there. Hopefully, one day, I'll be there."
Guentzel tied it 2-2 at 10:03 of the third period, tapping in a spinning backhand pass from Sidney Crosby, who has nine points (five goals, four assists) on a seven-game point streak.
“It was incredible. It’s one of the better ones that we’ve seen in a while,” Penguins coach Mike Sullivan said of the pass. “He has eyes in the back of his head. I don’t know how he knows he’s there or saw him. We grow accustomed to it. He makes so many plays, but that one was certainly a highlight-reel goal.
“We had quality looks. It seemed like a struggle to find the back of the net. I really liked our game in the third period. I thought the guys played real determined and we got a lot of momentum. Just a huge goal at a key time to give us an opportunity to get the win.”
