Juan Mata's future at Chelsea is again in doubt.
The People says manager Jose Mourinho wants Chelsea to make a £20million January bid for Barkley - but has been told he must sell first if he wants to land a major mid-season purchase.
The Special One wants Everton's England new boy to add dynamism to his midfield, and it is believed that Juan Mata's future at the Stamford Bridge club is still far from certain.
Mata could make way for Barkley if Chelsea receive an offer of more than £20m.
