Grealish curled home a brilliant goal for Villa in their most recent outing against Wigan Athletic.
And Parlour believes that if Steve Bruce can continue to get the best out of the talented youngster, then Villa will be in with a good chance of earning promotion.
“Jack Grealish has come in and got his goal. I think if Steve Bruce can get the best out of him, they will have a good chance of getting into the play offs,” the former Arsenal midfielder said.
When Bruce first took over at Villa, the claret and blues looked to be struggling to cope at Championship level, but they have been much improved over recent weeks.
Villa have lost just one of the first nine games which Bruce has been in charge of, to start moving up the Championship table.
The Villans are currently in 13th place in the second tier standings - and they are only four points back from the play off spaces.
Villa are next in action later this evening against Norwich City, and if they are able to get a win, they will move above Alex Neil’s men in the table.
