In 2009, it was reported that United continued to harbour plans to increase the capacity of the stadium further, with the next stage pointing to a redevelopment of the Sir Bobby Charlton Stand, which, unlike the rest of the stadium, remains single tier. A replication of the Sir Alex Ferguson Stand development and North-East and North-West Quadrants would see the stadium's capacity rise to an estimated 95,000, which would give it a greater capacity than Wembley Stadium (90,000). Any such development is likely to cost around £100 million, due to the proximity of the railway line that runs adjacent to the stadium, and the corresponding need to build over it and thus purchase up to 50 houses on the other side of the railway. Nevertheless, the Manchester United group property manager confirmed that expansion plans are in the pipeline – linked to profits made from the club's property holdings around Manchester – saying "There is a strategic plan for the stadium ... It is not our intention to stand still".
