The evolution of Ruben Loftus-Cheek to Ruben Wingback-Cheek has been quite something over the past four days.
Starting in that unorthodox role in Saturday's 6-0 thumping of Southampton felt like a wild experiment from Thomas Tuchel just for one afternoon, crammed between two Champions League legs. Like a Marvel side issue that isn't really canon in the narrative of Tuchel's Chelsea.
But on Tuesday night, he repeated the trick, again putting Loftus-Cheek in a hybrid wingback role. Floating inwards and outwards, covering vast amounts of ground in order to unsettle the returning Ferland Mendy. Although the academy graduate was not outstanding, the clever use of the midfielder proves how lucky the Blues are to have the German.
