I've heard about this before yes.
Komac is very good indeed, he's a midfielder, can play as right wing or offensive central midfielder, but in my opinnion he's better as a winger. He's really fast and skillfull, great work ethic, runs a lot, helps out defence. I'd concider him a great buy.
Under Oblak he became a standard NT member, and yes he did play against Scotland.
Kokot is a defender, a left back. He's also concidered as one of the best defenders in our league. I really couldn't say more about him as I don't know a lot, except for maybe that he also played for our NT once.
