And like anybody in that United dressing room he would have been left devastated with the 3-0 defeat against local rivals Manchester City last night.
Despite some flashes of improvement at the end of the day the result does not lie - City are a step or two above United in class at this moment in time.
Hernandez has not been given many opportunities to impress this season - featuring for just 574 minutes in the Premier League under David Moyes.
And he is also being linked with an exit from the club - so he might be forgiven for not exactly showing much care for the future of United, especially as he may not play a part of it.
But he took to Instagram last night to rid any such suggestion.
As the likes of Samir Nasri gloated and goaded Hernandez took to the social image upload site to thank the fans for their support and to suggest that United will not give up in their pursuit of becoming the best once again.
Bad result yesterday... Let's keep working... Thanks for the support to the team... You are the best...#nevergiveup
But it was difficult not to notice he had posted a pic of him taking a customary pre-match prayer as the attached media.
With Bayern Munich on the horizon, who won their Bundesliga title last night with a 3-1 win against Hertha Berlin, perhaps only divine intervention can prevent this campaign being a complete failure.
