The Turkish sports newspaper report that United have been keeping close tabs on the 14-year-old youth.
United were reported to have invited Cogalan to Carrington last week where they held talks with his father and representative during a trial.
The highly rated Turkish youngster scored 22 times and provided 30 assists for the Valencia youth side last season.
Cogalan has an agreement with Valencia until 2021 and his father has underlined that he will not rush into any decisions.
Ferhat’s father Sedat said: “We’re in no hurry because Ferhat is in contract with Valencia until 2021.
“But when a club like Manchester United invites us, it is logical that we study the proposal, right?”
The youngster was snapped up by Valencia aged 12 and has already broke into the Turkish national team youth setup.
Cogalan is tipped as being one of the brightest prospect in Turkish football and has already attracted interest from across Europe.
