Nylander is one of the biggest stars in the Four Nations beforehand.
With 33 goals so far this season, he is second in the NHL's scoring league.
If Sweden is to succeed, Nylander is one of the key players.
But the start was anything but fun.
Nylander received an unfortunate penalty already in the first shift in the overtime against Canada, losing 3-4, on Wednesday night. The result? A goal in the back already after 56 seconds.
It's nothing you can hang on to, then you'll ruin the rest of the game. It's just to forget and move on. It was sad that it turned out that way, but what can you do? We worked our way back, he says.
"Could have won"
It's the latter that Nylander and his team take with them into the hot rivalry match against Finland.
He thinks that his formation, the first line with center Mika Zibanejad and Rickard Rakell alongside Nylander, took big steps in the premiere.
We were just a couple of unlucky bounces away from scoring opportunities. I was close to getting two in overtime, so we could just as well have won. We'll develop our chemistry and we took steps already in the Canada match, he says.
The People's Enemy
Nylander was heavily booed in the presentation before the match – but takes it with a shrug.
As a Toronto player, he is not the world's most popular in Montreal.
It's just fun when you come to Montreal, a fun thing, he says with a crooked smile.
Toronto and Montreal are big rivals, just like Sweden and Finland.
He looks forward to the battle, which is simultaneously a must-win match for both teams to keep their chance of a final spot.
It's clear it's special, it's the team I've played the most matches against at national team level.
Finland fell big against the USA, 1-6, after collapsing in the third period with four conceded goals. The respect is still great.
I saw a bit, it was pretty tight, but then I saw it went fast in the third period. It's going to be a tough match, they have a really good team and good goalkeepers, he says.
