The playmaker is currently on loan at Leeds but has made a big impression.
The 31-year-old was one of a number of loan signings that the Whites made during the summer. But unlike the likes of Pontus Jansson, Kyle Bartley and Hadi Sacko, Hernandez's deal is only set to run for another few weeks.

The former Swansea man has impressed greatly during his time in Yorkshire, which has led to calls from many supporters for the playmaker to stay at the club for a longer spell.
And Monk has now suggested that it appears highly likely that the Spaniard will remain a crucial part of his team by the time the end of the January window rolls around.

"Very confident," he told BBC Radio Leeds when asked how confident he was of signing Hernandez permanently.
"Pablo's very committed to us here. He's enjoying his work. He loves being at the club. He's been valuable for us with his performances and his experience amongst the group and amongst the young players.
"He's a top player. He wants to commit and I'm sure it's all ready to go in January."
Making Hernandez's deal permanent will undoubtedly provide a major boost to Leeds' hopes of promotion this season. Though he has been inconsistent at times, he has shown on several occasions that he has the quality to inspire the side up the table.
He has contributed two goals and two assists in the league, and is the kind of player that can make something special happen out of nothing, which could be crucial as the campaign reaches the business end.
