Despite the controversy over the deal and some concern inside the Barca locker room, Bartomeu is pressing ahead with plans to sign Isco.
Don Balon says Manchester City are also keen, which is heaping pressure on Real management.
Real want Isco to stay, but are reluctant to match the €6 million-a-year offers Barca and City are willing to put on the table. Such proposals would treble Isco's current Real contract.
At Barca, while there is some opposition within the squad, Isco's arrival would have the support of Lionel Messi.
