Manchester City are looking to build a £300m arena next to the Etihad for concerts, NBA matches and UFC fights.
The stunning 21,000-seater already has plans drawn up and consultations with the public started last week, reports The Sun.
City would rake-in millions a year from the arena, which is expected to take up to three years to complete.
The project already has the full support of Manchester City Council and the majority of the surrounding residents.
City have spent around £400m in recent seasons investing in the local area, which is one of the most deprived in the UK.
The club’s owners have a long-term vision for the Etihad, combining leisure with further education.
They also have ambitions to build 5,000 affordable homes over the coming years to help the community.
The Premier League champions are working on the co-venture with American firm the Oak View Group.
Meanwhile, Man City continued their Champions League campaign last night with a 5-1 win over Atalanta.
