Joined the forum to say a few words about Kova, as someone who watched him for a long long time, this signing should excite you.
He wasn't a magician like modrić, but he is such a smart player in a weird way, and what I mean by that is he is almost like a computer program. Which makes him an amazing system player and is really coachable. Sometimes he was a victim of it which would lead to mistakes. What I am trying to say very poorly is you can tell Kova, you need to do these 5 things and he can turn his brain off and do those 5 things perfectly for 90 minutes.
And if you have someone like Pep telling him what to do is really exciting.
Bonus: A famous moment of that is during an El Clasico trashing he was tasked with playing man to man with Messi and follow him every step, and one counter Attack that was started and finished by Rakitic Messi figured that out and starting slowing down, drifting wide and not even trying to participate in the counter and Kova almost stopped, got confused because he could have pressured Rakitic but he was told to man mark Messi which made him look like a headless fly on the field.
