10. Napoli

January spending: £11.6m

Rafa Benitez was relatively busy at Stadio San Paolo, adding three defenders and a midfielder to his ranks at Napoli.

The signing of Jorginho from Hellas Verona was perhaps his most high-profile capture, but the arrival of Faouzi Ghoulam, Henrique and Anthony Reveillere have also helped strengthen his squad.
