Chelsea's January transfer window was something of a non-event. The Blues didn't make a single first-team signing nor did they let anybody depart from Thomas Tuchel's squad.
That was always expected to be the case in truth. Tuchel did want reinforcement at left wing-back in the absence of Ben Chilwell but there was only one candidate the German truly felt was worth pushing for in the transfer market: Emerson Palmieri.
Unfortunately, that didn't happen. And when Chelsea decided to give up on bringing the Italian international back to Stamford Bridge from Lyon, that was effectively the end of their transfer window endeavours.
