3) Pierre-Emerick Aubameyang (Borussia Dortmund)
With Jurgen Klopp having gone, no one’s quite sure what’s next for a number of the Dortmund stars, and Liverpool could take advantage by swooping for this impressive 25-year-old. The Gabon international scored 25 goals in all competitions last season, despite Dortmund’s poor form, and has not failed to reach double figures for the campaign since 2011. He’s finished second in the ‘African Player of the Year’ vote in 2014, behind Yaya Toure.
