If you type in Etihad Stadium you get the answer. The original name was the City of Manchester Stadium though, but yes you are correct, untill 2020 its called the Ethiad Stadium
100%. I think just Etihad should be accepted. Also there is no e in the Hart of White Hart Lane. And the Arsenal's stadium is called Ashburton Grove, but much like the Etihad Stadium, the Emirates Stadium is its official title for sponsorship reasons, therefore could you make that an acceptable answer as well. It was nice to see someone recognise The Boleyn Ground as the name for West Ham United's stadium as well. :D
