The Brazilian has been linked with a move away from the club, playing just 56 minutes since the resumption of football.
Having joined the club's academy in 2012, the 24-year-old has 75 appearances under his belt at Old Trafford.
But Esparto Interativo says the forward is already looking to secure his future elsewhere.
Manager Ole Gunnar Solskjaer had tried to convince Pereira to stay but his agent Kia Joorabchian had already been talking to clubs in Portugal, Spain and Germany.
The report goes on to states that Valencia president Peter Lim, head of the club that the Brazilian spent the 2017/18 season on loan, would welcome him back.
