The Villans suffered relegation to the Championship last season, but have been building for an immediate return to the top tier with the appointment of Roberto Di Matteo and the signing of Ross McCormack both notable moves.
And reports claim that Villa remain ambitious in their plans, with Hull’s Hernandez wanted.
The Uruguayan starred for the Tigers as they secured a spot in the top tier via the play-offs last term, notching 21 goals.
However, Hull are in disarray with the new season just over a week away, with no manager in place following Steve Bruce’s resignation and a lack of fit first-team players.
Villa are likely to find it difficult to persuade Hernandez to drop back down to the Championship, but they may take encouragement from Mohammed Diame’s move from the Humberside club to Newcastle this week.
