Martinez has also revealed that he boasts a special Messi memento that he will be saving for his daughter. He added on another experience with Argentina’s GOAT: “There is something I've never revealed in the media. There is a very special object I have saved for when my daughter turns 15. I'm not someone who takes photos with players; for me, all players are the same. I'm there to do my job. However, I went with the dressing room delegate to check some things during a match involving Messi.
“At that moment Leo Messi was there signing some things. I decided to take out the FIFA card with which I officiated in the Gold Cup final between Mexico and Panama. It would be a memento for my daughter, not me. As you can see on the card, it says: 'For Siham Martínez, with love, Leo Messi'. This is Messi's original signature; this is the precious object I have from him. It's Messi's handwriting. He took the time to write it. These details are worth more than gold; it's an invaluable memory.”
