Villa are playing in the Championship this season after getting relegated from the Premier League at the end of the 2015-16 campaign.
The Villans are 15th in the league table at the moment with 22 points from 17 matches.
Steve Bruce’s side are five points behind Norwich City, who are currently sixth in the standings and occupy the final playoff spot.
Newcastle United, who also got relegated from the Premier League at the end of last season, are at the top of the Championship table with 40 points from 17 matches.
Brighton & Hove Albion are currently second in the standings with 35 points from 17 games.
Grealish, who is 21 years of age and can operate as a winger or as an attacking midfielder, believes that Villa can clinch an automatic promotion spot.
“Promotion definitely,” Grealish told The Times when asked about Villa’s targets this season. “Automatic, definitely.
“We are five points off the play-offs [sixth-placed Norwich City]. But we have 29 games left. For all the boys in the changing room, when we talk about it, going up in the top two is definitely doable.”
There is a long way to go in the Championship this season and nothing is impossible, but it is hard to see Villa challenging for automatic promotion.
A top-two finish is quite a bold target; a playoff spot is more realistic for Bruce’s side.
