The 25-year-old has impressed for Valencia this season and Chelsea scouts have watched him in action.
“Chelsea? It is flattering to me because it demonstrates that I am doing well this season,” Hernandez told reporters.
“But now is not the moment for me to speak about this subject.
“As normal this news appears at the end of the season but the important thing for me is to continue getting victories for Valencia and to confirm our place in the Champions League.”
