Real Madrid president Florentino Perez has claimed that the club will announce the contract renewal of Isco in the coming days.
Isco has previously been targeted by both Manchester United and Tottenham Hotspur, while there is currently less than a year remaining on his current deal.
However, with the playmaker now established as a first-team regular at Real, Perez has revealed that fresh terms have already been agreed.
Perez told Cadena SER: "Isco arrived here when he was very young and all he has done is improve. He is currently playing as we believed he would turn out.
"We will be announcing his contract renewal in the coming days, a renewal which is a done deal."
Since signing for Real in 2013, Isco has netted 34 goals in 187 appearances in all competitions.
