Ortega signed for City in 2022 on a free transfer after ending his contract at Arminia Bielefeld, who had just been relegated from the Bundesliga. He replaced Zack Steffen, who had been an unreliable back-up to Ederson, making a big mistake in the FA Cup semi-final against Liverpool. Guardiola credited goalkeeping coach Xabi Mancisidor for recommending Ortega. "It was Xabi. It happened in the past, he introduced me to two or three keepers, I said okay, let's go. I'm not an expert on keepers, that's why I have trainers for that. He did really well."
