So back to the stadium question

[Crossie]

Nice article on it here,

During the 2010 closed season the football pitch and hospitality areas were renovated, with a £1 million investment being made in the playing surface so that it is better able to tolerate concerts and other events without damage.[69] In October 2010, Manchester City renegotiated the stadium lease, agreeing to now pay the city council an annual fixed sum of £3 million where previously it had only paid half of the ticket sales revenue from match attendances exceeding 35,000.[70] This new agreement occurred as part of a standard 5-year review of the original lease and it amounts to an approximate £1 million annual increase in council revenues from the stadium.[70]
For the current and previous seasons, the club has sold all 36,000 of its allocated season tickets[71] and is now looking at increasing the stadium's capacity. The club's agreement with Manchester City Council in March 2010 allows redevelopment around the stadium and possible stadium expansion to 60,000.[68] This increase in capacity could be achieved by adding a third tier of seats to the north and south stands so that they match the east and west stands. The stadium expansion is linked to the club's stated commitment to "potential development as part of a contribution to the regeneration of east Manchester"
