Man City have submitted a planning application at the Etihad which will increase the stadium's capacity to more than 60,000.
The Etihad - which was previously known as the City of Manchester Stadium and built to host the 2002 Commonwealth Games - currently has a capacity of 53,400 for domestic football matches.
City's plans - which have been submitted to Manchester City Council - are to expand the North Stand with one larger, single upper tier above the existing lower tier.
The application submitted by the club also includes the stadium becoming a new entertainment destination, with a covered fan zone with capacity for 3,000 people, which will include a variety of food and drink outlets, a new club shop, museum and a 400-bed hotel.
