day, the name maintains a good share of support among the fans. To further increase revenue, AZ's board of directors decided to expand the capacity of the new stadium to at least 30,000 somewhere in the future. The extension will be realised by constructing a second tier to three of the four stands. The main stand with all technical areas, VIP and sponsor and media facilities will remain in place. These plans, however, were put on hold after the DSB bankruptcy and there are no current plans to increase the capacity. In October 2009, sponsor DSB Bank was declared bankrupt. The stadium name temporarily changed from DSB Stadion to AZ Stadion, as it was considered undesirable that the stadium was linked with a non-existent bank. In February 2010, a new main sponsor was found in construction works service provider BUKO, based in Beverwijk. A year later, in the 2010–11 season, took over as official stadium sponsor. The current external name of the ground is the AFAS Stadion. On 10 August 2019, the roof of the stadium partially collapsed. No people were injured during the incident. As the result AZ spent the rest of the year playing home matches at the Cars Jeans Stadion in The Hague whilst the damaged roof was being removed, before returning to the stadium on 15 December 2019, beating Ajax 1–0 in their first match back. AZ played the rest of the 2019/20 season, until the COVID-19 pandemic cut it short, without a roof. During the 2020/21 season, a new roof was installed, held up by 20 crane-like arms on three sides and a so-called mega truss on the main stand. The renewed stadium, which also included a capacity upgrade of nearly 2,500 seats for a new total capacity of 19,500, was officially opened on September 11th, 2021, before the home game against PSV.
