But the Honduras international, who has an option to extend his contract in January, has targeted regular first-team football at Elland Road after turning down several offers in Mexico to ply his trade in England.
Nunez, 24, said: "I know I have come to a better club in Leeds. There is great tradition and I'm delighted to be here. My target is to get into the team as soon as possible. I want to be playing games in the starting XI - as anyone on the team does.
"But I know it will be very difficult for me to get into this Leeds team. They have been on a good run and there are a lot of great players on the field who are doing a great job. I have to do my job on the training field.
"But every team I have been on I have been able to score some goals and hopefully I can do that here at Leeds."
