The North London club were the closest they’d ever been to a Champions League title last season, only for Gabriel, 28, to miss the deciding spot kick.
Arsenal are among the favourites to win the most prestigious trophy in European club football this season too, and the Brazilian wants a shot at redemption.
Gabriel said to ESPN Brasil: "I couldn't let a single missed penalty erase everything I'd achieved during the season.
"I just thank God for the opportunity to have been there in that moment; it's part of football. "I'm definitely eager for another chance. If it happens again, I'll be there, and if I have to take the penalty, I'll take it. That’s it."
Arsenal beat Napoli 1-0 in their first game of the 2026-27 campaign and will host Lille in their next game on October 13th.
