The Daily Mail reports that the Gunners are keen to bring in Hernandez due to fears over the workload of Olivier Giroud.
The Gunners are short of striking options and are desperate to bring in a new striker in January.
Liverpool striker Luis Suarez remains Arsenal boss Arsene Wenger’s dream signing, but Hernandez is seen as a good alternative.
Hernandez could be interested in a move to the Emirates Stadium due to the lack of game time at Old Trafford.
