Santos Laguna striker Peralta said: "Yes, of course I'd love to come and play here. It would be a challenge and it would be really great for me."
Hernandez is one of few Mexicans to make a real impression in the Premier League and Peralta said: "He's an inspiration to us, scoring goals.
"We have to train to be like him. He scores many important goals for Manchester United. This makes us happy and it's something we aspire to."
