Competing at Arena Mexico for the first time lived up to Adam Copeland’s high expectations. Before Grand Slam Mexico, Copeland listed Arena Mexico as one of the things still left on his wrestling bucket list. Copeland made an Instagram post on Thursday reflecting on how much this Arena Mexico debut meant to him, saying it’s something he’ll cherish for the rest of his life:What. Arena Mexico. Copeland named Arena Mexico, Wembley, Maple Leaf Gardens, and the Tokyo Dome as the four venues he’s hoping to compete at before his eventual retirement.
