The Santiago Bernabeu side have confirmed the capture of the Spain Under-21 international from Real Sociedad, with the midfielder penning a six-year deal
Both clubs had been in talks over a transfer for a number of weeks, with la Real's insistence that Madrid met the 23-year-old's buy-out clause initially holding up the deal.
However, los Blancos have confirmed on their official website that the deal has been brokered and Illarramendi will sign a six-year deal with the Santiago Bernabeu side upon completion of his medical on Saturday.
"Real Madrid C. F. has hired Asier Illarramendi, who will now be with the club for the next six seasons. The player will be presented tomorrow - Saturday, July 13, at 13:00pm in the Royal Box at Santiago Bernabeu stadium, after undergoing the relevant medical examination.
"On this day, Real Madrid C. F. paid Real Sociedad an amount of €32.19 million for the acquisition of the federal rights of Asier Illarramendi. This operation, as in all transfers of players between Spanish clubs, is subject to current VAT of 21%, which means no cost to Real Madrid C. F, since this amount is deductible from the club's VAT settlements."
Illarramendi is a product of the Sociedad youth academy and had developed into a key player at the Basque side since making his official first-team debut in June 2010.
The midfielder was an integral part of the Spain Under-21 squad that were crowned European champions in Israel this summer.
Illarramendi becomes Real Madrid's fourth signing of the summer transfer window after the previous capture of Casemiro, Isco and Daniel Carvajal.
