Although the Blues have been strongly linked with Fiorentina winger Juan Cuadrado recently, the Guardian claim the Italian side are unwilling to sell for less than the £26.8m buyout clause, which has forced the London club to rethink their options.
Although talks with Fiorentina are ongoing, Chelsea have also approached Shakhtar and have indicted that they are happy to part with £20m for Costa’s services, report the Guardian.
Any January purchases are dependent on Blues boss Jose Mourinho offloading some players first, with Mohamed Salah and Andre Schurrle both being told that they are free to leave the club in the transfer window. Salah is attracting interest from AS Roma – who are hoping to tie up a loan deal with a view to making it permanent in the summer – while the unsettled Schurrle is reportedly keen on a move back to Germany.
Douglas Costa has made nine appearances for Shakhtar this season, scoring one goal.
