Bent's switch to Villa was completed on Tuesday for an initial £18million three days after the striker put in a shock transfer request. Sunderland boss Steve Bruce claimed Bent had been unsettled and chairman Niall Quinn has revealed he feared three weeks ago that the 26-year-old had his mind elsewhere.
But Villa issued a strongly-worded statement stressing that there had been no "inappropriate approach" to the player.
Quinn told Kildare TV: "I had an inkling. Darren is a terrific guy and he has been great for us. He's done loads of work with us for the club over and beyond just playing football. He's bubbly and he's always on great form.
"Two or three weeks ago maybe, I went into the training ground and there was something up with him. I looked at his demeanour and I thought, 'It's not right'. Having been in the game, you kind of know when someone's got something going on in their heads.
"It transpired that that's what had happened. They were setting him up to try and come and he took the bait. It's hugely disappointing for us, but all we could do then was battle hard and, when the transfer request came in, that was probably the final nail.
"We could have tried to stop it. It was really difficult. The only job left to do was get as good a deal as possible for the club and to start finding a replacement and a solution to the problem he's given us."
Villa reacted to Quinn's comments by insisting the player did not know about any possible deal until after the 1-1 derby draw with Newcastle on Sunday.
"We understand Sunderland Football Club's need to explain to their naturally-disappointed supporters why Darren Bent has been allowed to leave their club," read the statement.
"It is disappointing, however, that Sunderland should try to besmirch the reputation of the player and Aston Villa Football Club in the process. We wish to make clear that at no time did Aston Villa make an inappropriate approach to the player or unfairly compromise the business of Sunderland Football Club."
