Chelsea are set for a busy final few days of the January transfer window as Jose Mourinho plans to sign three new players for a combined £70m. The Blues are close to completing a £27m deal for Fiorentina winger Juan Cuadrado, but are also keen to bring both Douglas Costa and Enner Valencia to Stamford Bridge. Shakhtar Donetsk value Costa at £22m, and they'll also be required to pay £21m if they are serious about luring the Hammers striker from Upton Park. Meanwhile, Andre Schurrle is set to seal a swift departure from west London, with the World Cup winner heading back to Germany to join Bundesliga outfit Wolfsburg for a fee in excess of £20m. And finally, Chelsea will have to wait until the summer to sign Kevin Strootman after the AS Roma midfielder confirmed he's set for another spell on the sidelines with a fresh knee injury.
