Graham Potter's issues in the middle of the park has been one of the biggest he's been tasked with since succeeding Thomas Tuchel in September. Without N'Golo Kante due to injury and Mateo Kovacic struggling for fitness, the Blues have lacked depth in the position.
The Blues do possess Jorginho and Ruben Loftus-Cheek in their ranks while Denis Zakaria is still yet to be handed his debut since his late summer loan move from Juventus. However, away from the four mentioned, the position is one that is desperate to be addressed in the January transfer window.
It's a well-known fact that the current crop of players at Cobham are unable to defend on their own due to the neglect of the defensive midfield position throughout the years. Since taking over, Potter has realised what previous managers have had to suffer with and the 47-year-old is keen to end the common theme.
