Sorry, I meant all of our competitors .. which they do. Dembele used to be our man who could compete with the best CM's, he isn't any longer, at least not reliably.
Everybody else aiming for top four has aimed to bring in quality central midfielders. Liverpool brought in Fabinho & Keita, City went for Jorginho but still have Gundogan, De Bruyne and Fernandinho, United have Pogba, Chelsea have Kovacic, Kante, Jorginho .. etc.
Like I said, even Arsenal went in and paid good money for a highly rated player in Torreira.
