Souness was speaking after United's rout of Leicester City.
"What I think Pogba should be doing is getting in front of the ball a lot of the time. Making runs into the box. For me it looks like he can run all day, he looks like a real athlete," Souness told Sky Sports.
He added: "I just think it's like he is playing well within himself. I just think he has got so much more to offer and I'd like to see him in amongst the goals more, getting forward and being a real threat."
