Pogba has been on Real's radar for much of the year, where coach Zinedine Zidane is determined to work with him in Madrid. The pair were snapped in October meeting in Dubai.
However, Mundo Deportivo says Perez doesn't share the same enthusiasm.
Indeed, the only way the president will push to sign Pogba is if United agree to dramatically slash his asking price.
While United vice-chairman exec Ed Woodward has been demanding €150-200m to sell their World Cup winner, Perez has let it be known with intermediaries he doesn't regard the midfielder as worth anymore than €50m.
