I was on the stadium tour this afternoon and the tour guide actually mentioned the proposed North Stand expansion in such a matter of fact way that you couldn't possibly believe that it wasn't going through happen.
He also asserted that the recent capacity reduction was due to City needing more advertising space for TV revenue during the COVID period when crowds weren't allowed inside the stadium.
Apparently the ETIHAD needs a larger capacity before the club can apply for World Cup games and Champions League Finals, and if it wasn't for COVID, the planning permission would already have been sorted (he gave a timescale of 1-2 years from now)
Mind you, he.then conveyed an anecdote regarding Aguero and a 2-0 defeat to Schalke, so perhaps everything he said was bollocks.
