The Uruguayan forward joined the Tigers in 2014, but despite his impressive record in Italy with Palermo he was unable to help the Humberside outfit avoid relegation to the Championship.
Hernandez has since stayed at the KC Stadium and has netted 15 league goals for the promotion-chasing side in league action, and reports claim that this form has alerted Arsenal.
Gunners boss Arsene Wenger is known to be short of genuine centre-forward options, with Olivier Giroud the only orthodox option at his disposal.
Hernandez, 25, possesses the pace and power to lead the line and has demonstrated his finishing ability in the second tier, hinting that he has somewhat adapted to English football after a difficult debut season – in which he netted four Premier League goals in 25 outings.
