Real Madrid will leave Sergo Reguilon at Tottenham this summer.
Real have a buy-back clause in Reguilon's deal and there has been talk of triggering it at the end of this season.
However, El Chringuito says the €40m needed to re-sign Reguilon is deemed too rich.
Instead, Real are pursuing another former player in Rayo Vallecano left-back Fran Garcia.
In contrast to Reguilon, Fran's buyout clause is set at €5m.
