Call it the domino effect. One move can lead to many more. If Chelsea had not gone for Maurizio Sarri, N'Golo Kante might be anchoring their midfield today. Until Chelsea appointed the Italian, Manchester City were confident of signing Jorginho from Napoli.
Instead of rivalling Fernandinho for a place, he is his opposite number. If Jorginho, as the face of Sarri's Chelsea, is perhaps the most transformative player in this season's Premier League, he offers two clashes of styles, with teammate and opponent, each a more conventional defensive midfielder.
