The chance of Sydney FC building their own boutique stadium appears to be unlikely after the club agreed to a new long-term deal to stay at Allianz Stadium for the foreseeable future. For the next 10 seasons, the Sky Blues will continue to play the majority of their A-League games at their current home despite the ongoing uncertainty of the venue's capacity and facilities under the NSW government's $1.6 billion stadium renovation project.

It is understood SCG Trust have agreed in principle to a new lease deal with the Sky Blues in what it describe as a major coup in retaining the biggest permanent tenant of Allianz Stadium until 2026. The club declined to comment when contacted by Fairfax Media, however sources suggest the agreement is expected to be signed in the coming weeks and will include a significant reduction in tenancy costs for the club. Of the three permanent tenants of Allianz Stadium – Sydney FC, Sydney Roosters and NSW Waratahs – the Sky Blues attract more fans through the turnstiles and host more home games during the regular season.

Allianz Stadium is third in line to receive funding for renovation after Parramatta Stadium and ANZ Stadium, but the SCG Trust's hopes of fast-tracking renovation approval have been boosted by the security of Sydney FC's tenancy for a further 10 years.

Despite the club having never played regularly at another venue it's understood the SCG Trust was at risk of losing Sydney FC, who were looking at other options before agreeing to stay at Allianz Stadium. Under previous tenancy deals, an attendance of nearly 15,000 was required for the club to break even on match costs and rent, which prompted other suburban grounds to be explored, as well as the possibility of building their own stadium.
