MUST SEE: M. Tkachuk chases Hischier down the ice for revenge

On their first meeting, both teams' captains met for a draw. Nico Hischier went down hard to try and win the face off and ended up hitting Aleksander Barkov's knee, you'll be the judge of whether there was an intention to injure or he juste wanted to win the draw. Barkov painfully left the ice afterwards, here's the clip:

The met again last night and newly acquired Matthew Tkachuk doesn't forget that easily. When a brawl breaks up at the end of the game, he chases down Hischier to try and make him pay.

Tkachuk has alway been known for his physicality, but was this attack premeditated? Was it really deserved? Tkachuk's never been known for his ‘'clean'' play, but did he go overboard on this one?
