Talking to Onda Vasca, Martinez opened up about his surprising move to Saudi, admitting that it wasn't an easy decision for him and his family.
"On a financial level, you can't compare that league with any of the others these days," he said. "Looking at my career and what I'd achieved, it was time to take the step. A player's journey is short: I'm 34 years old, and these trains come once, if they come at all, and it's hard to say no. The moment you see the offer, you can't even believe it: no one is prepared for that. I had been a pawn in football. You have to be there to understand what an offer like that is."
He added: "I certainly would have thought about staying if I'd had more years with Barça. Because my salary was significant, not that it was a low salary, and we were happy. Whether you like it or not, coming to this country... it's a tough decision to make; not only dragging my wife along, but also my children, everything changes. Maybe I would have thought about it more, yes."
The quick change from expecting to stay at Barca to joining Al-Nassr came as a shock, saying: "Look, it came as a surprise to many. And aside from the fact that I got on well with the fans, I generated that excitement, and in the end, my leaving came as a surprise to them, but that's how football works, and these days we're used to changes happening overnight."
