The Mexican international joined West Ham this summer and the fixture list has left him with a bit of a dilemma if he scores.
He said: "Imagine the emotions I have in that moment if I have the luck to score there. It is my old club, with my old fans in my old stadium so probably I cannot celebrate. But as well it will be my first goal coming back to the Premier League with a club that has shown a lot of confidence in me.
"I do know I would love to score a goal and help my team to get a result."
