Martinez told Star+, via ESPN: "Look at the look on this kid's [Tchouameni] face, tell me he's not nervous, I saw that he was dead in front of goal. And I thought that if he missed, they were half a step off and we'd be champions. And he was looking up, looking at the people, he was very nervous, and I had practised it with my psychologist, if I managed to save one, the next one I'd make his life impossible. And if I went to the goal, I'd save it, it was mine, I'd taken a really good shot, I'd pushed myself really well, if I grazed it, I'd take it out."
The 31-year-old also spoke about practising to save Coman's penalty - something he pulled off.
"I shoot high in the 90' (minutes) and low in the shoot-out. And he [Coman] goes up in the shootout, and down in the 90'. But I was calm because I knew that by saving one I was going to put them under pressure, so that was key. On top of that I missed it, I didn't save it with my hands, I pushed it with my chest and it went through my hands," he added.
