The Blues midfielder secured titles in back-to-back seasons, both as an integral part, and is now wanted by Paris Saint-Germain, reports the Mirror, with the Ligue 1 giants lining up a £90 million move.

The 26-year-old could return to his home town in a deal that would make him the most expensive Premier League export of all time -- surpassing Gareth Bale's £86m move to Real Madrid.

After assembling an all-star front line following moves for Kylian Mbappe and Neymar, PSG now want to give Unai Emery a general in the middle of the pitch to give them a platform to shine.
