So i'm wrong thinking Meunier is more solid defensively than Sidibe, while Sidibe is better in attack? A genuine question, since I know you've seen much more of both than me.
Yes, Meunier isn't solid defensively and he isn't better than Sidibé, the only difference is that the right back for PSG isn't used like the right back for Monaco. If Meunier was more solid, it would be marginal but I don't think that even is and Sidibé is better going forward. There isn't a lot between them but Sidibé has more variety partially due to the fact that he can use his left foot without trouble.
