Watched quite a few, as I did Mangala before we signed him.
Mangala and Koulibaly share a lot of the same physical and defensive traits, Koulibaly is better on the ball which of course is a huge plus for us.
Serie A is shite so seeing Koulibaly dominate them games is understandable and he has had a few stand out CL games also but so did Mangala at Porto.
Koulibaly being better on the ball is an understatement. It’s night and day, Mangala was terrible on the ball and Koulibaly is one of the best around.
Koulibaly had many stand out games in the CL, Mangala the majority of fans never even heard of prior to us signing him.
the only thing they have in common is physicality and pace.
