Koulibaly added: “When I came, I was thinking this league would be easier than others, but I was surprised about the standard of my team-mates, and surprised at the level of the league. Even clubs that don’t have big, big-name players are very good – it’s difficult to play against them all. The level is not quite the same as Europe, but over time it will get there because the players will want to come and improve the league.”
