Chelsea have struck terms with Valencia for Juan Mata.
Neither club has disclosed the fee for the 23-year-old but both confirmed the transfer was subject to the player passing the relevant medical tests.
Chelsea's statement read: "An agreement has been reached with Valencia CF for the transfer to Chelsea of midfielder Juan Manuel Mata.
"The move is now subject to the player passing a medical and agreeing personal terms."
Valencia's statement was almost identical in wording.
