While Juventus have recently emerged as favourites for the France international, the Bernabeu remains a potential destination for the World Cup winner.
However, Stielike, who represented Los Blancos between 1977 and 1985, feels that the Pogba is not 'humble enough' to play for the Spanish giants.
Speaking to AS, the 65-year-old said: "If you want to return to the idea of the Galacticos, maybe yes, but I am more in favour of humble players with great talent and sacrifice for the team."
Although United have the option of extending Pogba's contract past 2021, it remains unclear whether club officials will opt to enforce that clause.
The 27-year-old has only made eight appearances in all competitions this season. body check tags ::
