Just been reading about St. Mary's on Wikipedia and it says in reference to possible expansion the following
All stands bar the Itchen can be built upon and expanded if ever deemed necessary, which would give an approximate capacity of around 50,000. However this would cost a similar amount to how much it cost to build the stadium in the first place.
However, due to the upcoming Rugby World Cup, the stadium could be expanded to around 45,000 - 50,000 by the IRB as it has been chosen to host pool matches during the Rugby World Cup. The club will not pay anything for the expansion, however this is all subject to approval and planning permission.
It says citation needed which gives the impression that its all fabricated but does anyone know if there's actually any truth in this?
Sorry if its been asked before I couldn't find it in search.
