Julio Martinez has signed with Chicago Fire on loan from Mexican second division club Leon FC.

The midfielder played under new Fire coach Carlos de los Cobos when he was at the helm of the El Salvador national team and he is delighted the 24-year old has joined his team.

"Julio is a true professional with a winner's mentality who will come in and help our team," said de los Cobos. "I could not be happier about his signing and look forward to incorporating him in with the rest of the guys."

Fire technical director Frank Klopas echoed the head coaches sentiments, saying: "Martinez is an exciting player who's known for his middle-range shooting and ability to score goals. I think he'll make an excellent addition to our roster."
