"They have some big forwards who can really grind you out," he said. "We need to stay positive on the bench. Against Boston especially, it's a team that doesn't give up much. We have to adjust to a big team that plays well and is coached well."
Vanek has been particularly successful against the Bruins in his career with 62 points (30 goals, 32 assists) in 55 career games.
"You have to beat some big teams to get the ultimate prize, and this is one of those teams," he added.
The Canadiens won three of four games against Boston, including both games at TD Garden. The Bruins have taken seven of the last 11 playoff games between the clubs.
"What the Boston Bruins have done in the last few years in the playoffs is as good or better than any other team in the league," said Gorges. "They've won a Stanley Cup in the last (three) years, they were there again last year, they won the Presidents' Trophy ... we haven't accomplished any of that. We're trying to surpass the top team. We know we have a great job ahead of us."
In their most recent postseason meeting in 2011, the Bruins won Game 7 in the first round in overtime. Boston went on to win its sixth Stanley Cup.
