Don Balon says Perez has told fellow boardmembers that Pochettino is his top choice to succeed Zinedine Zidane at the end of this season. Should Real finish the campaign trophyless, Zidane will be asked for his resignation.
Perez has been informed by his intermediaries that Pochettino will say 'yes' should Real offer him the job.
However, he also knows great rival Daniel Levy, the Spurs chairman, is determined to keep hold of the Argentine and could increase both his contract and his transfer budget to convince the Argentine to stay.
But Perez has been encouraged by recent comments made by Pochettino about Jorge Griffa, the former Atletico Madrid defender and Argentina coach.
"Football will take me where football wants, Jorge Griffa , who is like a father to me, told me: 'Do not think too much, enjoy the present and be professional and responsible, let football take you where it wants'," said Pochettino just last month.
