Malaga boss Javi Gracia is reportedly ready to build his team around Pereira having made him a top target.
The Brazilian reportedly wanted a loan move away from Old Trafford in the winter transfer market but he was denied his wish by van Gaal amid an injury crisis at the club.
Pereira is a huge talent and one that is too good to play in the U21s but there is a question mark over his attitude.
Perhaps a loan move would be better for the youngster as United may come to regret their decision if they do let Pereira go. Paul Pogba left Old Trafford for Juventus for free in 2012 and he is now considered to be one of the best midfielders in the world.
