The father of Isco doesn't expect him to leave Real Madrid in January.
The midfielder is a major January target for Tottenham.
"We've opted to keep a low profile with the press and I can assure you that we are not going to consider any offer before next summer," Paco Alcarcon told Calciometro.
With Real Madrid banned from registering new players until 2018 even a departure next summer could be difficult for Isco. However the 24-year-old's contract has less than two years left to run and it may be that the Spanish giants have no choice but to sell should the midfielder wish to depart.
