Premier League leaders Chelsea are expected to confirm the signing of Fiorentina's Juan Cuadrado with Schurrle having been tipped to depart Stamford Bridge throughout the transfer window.

Schurrle moved to Chelsea from Bayer Leverkusen ahead of the 2013-14 season.
However, he has been restricted to just five Premier League starts this term after falling down manager Jose Mourinho's pecking order.
