Stones better than Matip ? They are both ball playing defenders , but Matip is better at actual defending . Only thing Stones has over him right now is his huge potential . Bailly is good , but he got a lot of praise simply because he was an expensive signing for the most hyped up club in the summer , while Matip flew under the radar until recently , and did a similarly good job . Same for Mustafi . All those were in the centre of attention because of their price tags and the clubs they sign for , but have they actually been better than Matip this season ? In general it ' s pretty hard to judge , because they play in different systems , so it ' s pretty stupid to make conclusions of this sort . At the end , they are all doing perfectly fine in teams that suit their playing styles best . The one above all defensive summer signings has to be David Luiz . He started off in a typical Luizesque fashion , but he is part of one of the best defences I ' ve seen in recent times , while posing a serious goal threat . I still think he wasn ' t a good transfer decision at the time , but Conte managed to adapt himself to the squad he ' s got and brought the absolute best out of this team .
