Robson believes Pogba could miss out on a spot in United's best starting XI this season.
He told talkSPORT: "I would probably go with Fernandes, (Nemanja) Matic and De Beek [in central midfield] and just see where they go with it.
"We've got Scott McTominay, Fred who can do that holding role. Then you've got Pogba.
"I thought Paul started off poor even though he finished the season really strong. Maybe it is just a matter of time for the lads to get going. But the last thing you want is playing catch up to Liverpool.
"Pogba, Fernandes and Van de Beek, can you get the three of them in the team? Only time will tell."
