The Belgium international has been continuously linked with a move away from Villa Park but Bacuna questions whether he will be the main man at a bigger club like Liverpool.
"We had a small conversation about things. And I said, 'Imagine you want to leave for a big club...'" said Bacuna.
"At Villa he's the big man. Maybe if he goes somewhere else you are not going to turn into a big man. So it's going to be his opinion."
