Chelsea boss Ancelotti convinced Roma will sell Mexes
The Sun says Roma are willing to do business for the centre-back at around £12million.
Boss Ancelotti, a former Roma player, knows the Italians need to cash in after failing to qualify for the Champions League.
Frenchman Mexes, 27, has been one of Italy's top defensive imports since he signed from Auxerre in 2004 for £5m.
And he fits into Ancelotti's plans after Ricardo Carvalho made it clear he wants out of Stamford Bridge.
