A few days ago I decided to watch the AFCON final and I got really impressed by Koulibaly's performance; he was everywhere on the pitch and played and lead his teammates with exemplary composure ! Having watched the game I decided to buy Koulibaly's headliner card and see how he feels in game, I already had Next Generation Theo in my club and TOTYHM Edou Mendy was my starting keeper at the time so linking him wasn't an issue but I was a bit concerned about his dribbling and passing stats, regardless I was so hyped up from the AFCON final that I decided to buy him and try him anyway.
I am really impressed by this card, his passing and dribbling feels much better than the stats suggest and the only reasons that I can think of are either fake stats, his unique body type or both. as his partner I have TOTYHM Rudiger (top defender btw) and Koulibaly's transition feels just as smooth as Rudiger's; he feels super fast, moves around the pitch with ease and and thanks to his high defensive and physical stats + top tier tackling animations he makes defending easy and fun for you !
Overall along side Rudiger he's the best defender that I've had this year and since he's link-ability is decent (easy enough to get him to 8 chem) I fully recommend him if you're looking for a reliable CB.
I already mentioned that I use him along side Rudiger and I have to admit that I can't decide which one has the better card, one thing for sure they are both among the very best CBs in the game !
