\u201cBefore the match I knew about Jannik\u2019s quality. A great guy, a great champion. Already what he has done in his young career, it\u2019s pretty impressive, so I knew it was going to be a tough one. But even with that thought, I came to the match to win it, and actually having a winning mindset,\" Mensik said.<\/p>\r\n\r\n
