Be it through the injury to Ruben Loftus-Cheek, the exposed flaws of Jorginho, the stone wall in front of Frenkie de Jong, Billy Gilmours likely departure or the desperation to move on from a three man defence, Chelsea could yet sign a new midfielder this window.
After being broken apart by Southampton in the first half and toothless in the second, Chelsea needs someone to sit in front of the defence and break apart attacks. Not only working as a defensive shield but also allowing further expansion and flexibility in attack became apparent.
If it wasn't known already, it was made visible for all at St Mary's as Jorginho made a weak attempt to disrupt Ralph Hasenhuttl's side in the build-up to the winning goal. Chelsea have needed a new midfielder for several years, and with less than two days to go until the end of the window, they have kickstarted their attempts to bring in Ajax's Edson Alvarez.
