Agree with this. Pogba is ridiculously productive when in advanced positions, even in his periods of poor form when he gets on the edge of the opponents box he’s creative and helps greatly in sustaining attacks.I enjoyed his partnership with Shaw. I think Shaw played much better with Pog than Rashford because of Pog's decision making and the way he was finding him or putting him through.
I really think Rashford should stay on the RW and Pogba should play the LW role interchanging with Bruno to add confusion for the opp. Switching with Rashford occasionally. It would add dynamism and unpredictability.
In my opinion Pogba would have more output than both Rashford and Martial from the LW position, certainly from an assist perspective.
