Chelsea have struggled with injuries in midfield, with Tuchel being forced to play Reece James in midfield.
With Kovacic and Kante both struggling for fitness this season, outside options and potential transfers are being rumored about.
However, Chelsea already have the very impressive Conor Gallagher on their books, despite him being loaned out to Crystal Palace.
This has been suggested as a possible option, with many fans clamoring for a recall in January.
However, according to Chelsea correspondent Sam Inkersole, Gallagher is not expecting to cut his loan spell short.
Gallagher has 4 goals and 3 assists in the league this season and the youngster likely wants to continue growing with Palace.
