United have been tipped to launch a summer bid for Grealish as Ole Gunnar Solskjaer looks to put the finishing touches on a squad rebuild at Old Trafford.
Villa have reportedly placed an £80 million ($100m) price tag on a prized asset to ward off all potential suitors, but the Red Devils could end up securing a cut-price deal if Dean Smith’s side are relegated from the Premier League.
Bent insists there is no place for Grealish at Old Trafford while a world-class duo are pulling the strings in the middle of the pitch, with United also currently boasting the most prolific attacking trio in the top flight in Anthony Martial, Marcus Rashford and Mason Greenwood.
The ex-Villa striker told talkSPORT:
“I can’t see him getting in that United team. Just because there’s no way on the planet United could have them three in the middle of the park – Fernandes, Pogba and Grealish because defensively they would get run all over.
“I just think, you look at their front three – Martial, Rashford and Greenwood – he is not going to get in up there.
“I am not quite sure United need him in midfield if I am honest. He has got all the ability but he is not going to take Fernandes’ spot or Pogba’s and you are not going to put him in there as well. Pogba doesn’t really want to play holding midfield.”
