1. Van Dijk came in and solved Liverpools defensive issues. Laporte came in and solved many of our problems as well.
2. Zinchenko played WITH LAPORTE last season, when looking at their actual defending its clear Zinchenko isn't fully right there, he's okay, but Mendy is better and his whole body is better suited for it as well.
3. Mendy has been injured, and is coming back from injury, other than one mistake against Wolves he has been great coming back. Before his injuries he was also phenomenal for us, we bought him for a reason, his crossing ability is amazing, and he has power and pace.
I am starting to think you are probably not a troll, but hopefully you understand now why Mendy is an asset to City, and how important Laporte was for us.
