Aston Villa have already spent £12m to sign Ross McCormack, but they have now launched a £20m bid for Hull striker Abel Hernandez.
Aston Villa are keen to bolster their squad ahead and are set to smash the Championship transfer record, should this deal go through.
Hernandez, 26, was prolific as Hull were promoted from the Championship last season, scoring 22 goals, and he has one for the Tigers in the Premier League so far this season.
The local newspaper, Hull Daily Mail, have reported that the club are keen to keep him, with a lack of options themselves, but could look to reinvest such a hefty fee in further signings.
Hull are trying to sign Derby midfielder Jeff Hendrick and Tottenham’s Ryan Mason, after a strong start to the season of two victories and a defeat to United from three games.
Villa have so far signed James Chester from West Brom, Tommy Elphick from Bournemouth, Pierluigi Gollini on a free transfer and Reading’s Aaron Tshibola.
