Chelsea are reportedly interested in signing Marseille midfielder Gianelli Imbula in the January transfer window.
The 22-year-old is widely regarded as one of the best young talents in European football, with his performances this season drawing a host of attention.
According to The Express, Chelsea want to sign the Belgian-born midfielder in the winter transfer window, but will have to part with at least £25m.
Despite being born in Belgium, Imbula has made five appearances for France's Under-21 side.
