17) Pierre-Emerick Aubameyang (Borussia Dortmund to Chelsea)
Supposedly available at a bargain price of just £7m, Chelsea have been strongly linked with a move for Borussia Dortmund forward Pierre-Emerick Aubameyang. The Gabon international only joined Dortmund last summer, but is seemingly unsettled in Germany and his club have decided to allow him a move elsewhere. Chelsea are his strongest admirers as they seek to continue bringing in new attacking players, and a move could be done in the near future for this talented player to arrive at Stamford Bridge.
