But the Burnley midfielder admits he wouldn't have been able to keep the club up 'as great as he thinks he is.'
Indeed, former Villa boss Gregory recently emphasised his claim that Barton should have been snapped up on a free by Villa this summer. Many supporters agreed with him, although the Burnley man feels there were far less advocates of the switch at the time.
And Barton told the BBC: "There was an article in the Birmingham Mail this week where former Aston Villa manager John Gregory said the club should have signed me in the summer - and 78% of their fans agreed with him.
"I think Gregory has said that on numerous occasions, though, and the percentage of Villa fans to agree has gone up each time - when he first said it last summer, it was only about 20%.
"Hindsight is a wonderful thing but the reality of it is that, as great as I think I am, I don't think even I am good enough to play in that side and keep Villa in the Premier League."
Similar thinking to Gregory's, of course, brought Joleon Lescott and Micah Richards to Aston Villa.
And, as bad as some of the Midlands club's foreign signings have been, the defensive duo are proof Premier League experience doesn't always work.
Next up for Villa is a trip to Swansea City on Saturday evening. Barton, meanwhile, will host Wolves on the same day with high-flying Burnley, who currently sit top of the Championship table.
