Evaluating Messi's goal history

I need to be accurate. Reflecting on my memory, some articles claim Messi scored against Angola, but his first senior international goal was actually against Croatia in March 2006 during a friendly match. I’ll check who else scored in the Angola game—it could have been Maxi, Riquelme, or even Saviola. To stay precise, I’ll confirm details about subs and Ayala's caps, but might hold off on uncertain scorer details and use "2-0" for clarity.
