It looks like we have a new beef in the NHL. 

Washington Capitals forward Lars Eller and Boston Bruins forward Brad Marchand clearly don't like each other. 

It probably goes back to Eller's days with the Montreal Canadiens, however the beef really took off during the season opener when Eller showboated after putting the Caps' up 7-0 against the Bruins this season. 

“He took an angle in front of our bench and celebrated in a 7-0 game,” Marchand said of his rationale. “So I just let him know.”

"Let him know" meant pummelling him bloody. 

During their first meet up since that game, Eller wouldn't say pregame if he was seeking revenge, however he clearly was but Marchand wanted no part of it. 

“He obviously didn’t want any part of it. Everybody saw,” Eller told reporters at TD Garden following the game. “I would’ve rather fought him, but you can’t fight a guy that doesn’t want to fight. I mean, everybody saw what he is. I don’t know what else to say. We got out of here with two points. We got what we wanted. I don’t think there’s a lot of integrity in his game.”

Marchand's explanation was clear and made sense. 

“He plays, you know, maybe 10, 12 minutes a night and I’m playing 20, so in a 1-0 game, to go on the power play, it doesn’t make a lot of sense, so that’s the way it is,” Marchand said Thursday in response to Eller. “I will not concern myself at all with his views or his opinions. I’m not even going to engage in this battle because it means absolutely nothing to me. So that’s Lars’ views and he’s entitled to that,” Marchand said.
