Barnes believes that Grealish’s performances at Villa could increase his chances of earning a call to England and moving to United alone will not help his case.
The former British international insists that the young man’s decision should be based only on what is best for his career rather than on his chances of joining the Three Lions.
Barnes added: “It depends on whether he will be a regular at the first team at Manchester United, playing every single week and being a main player at Manchester United.
“He is the main player of Aston Villa and we can all see what he does if he goes to United where Pogba, [Anthony] Martial, Rashford are the main players, will it have such an impact?
