Chelsea are reportedly looking to beat a host of rivals to the signature of Borussia Dortmund striker Pierre-Emerick Aubameyang.
The 26-year-old Gabon international is one of Europe's most in-form forwards with 23 goals in 21 appearances this season.
According to The Sun, the Blues have been watching Aubameyang and are considering a £20m bid when the transfer window reopens in January.
Arsenal and Liverpool are also said to be interested in the former Milan and Saint-Etienne man.
