The clubs billionaire co-owner Jim Ratcliffe, says the structure could be built within five years and would be the world's greatest football stadium.It remains unclear what will happen to the Premier League football clubs current Old Trafford ground, which has been its home for the last 115 years.In 2024 Manchester United officials recommended building an all-new stadium, at a cost of around 2 billion, rather than upgrading the existing structure. It concluded that refurbishment would cost between 1 billion and 1.2 billion and reduce stadium capacity while works took place.AdvertisementDescribing his vision for the all-new stadium, Fosters founder, Manchester-born Norman Foster, 89, said: It starts with the idea of making something which is so intense it brings you close to the pitch. Acoustically it cultivates the roar.As you move away from the stadium, it is not a fortress surrounded by a sea of cars. Its contained by an umbrella that harvests solar energy and rainwater and encloses arguably the largest public space in the world.Ratcliffe added: Our current stadium has served us brilliantly for the past 115 years, but it has fallen behind the best arenas in world sport. By building next to the existing site, we will be able to preserve the essence of Old Trafford, while creating a truly state-of-the-art stadium that transforms the fan experience, only footsteps from our historic home.Fosters, which famously worked on the new Wembley stadium, has also drawn up a masterplan for the areas around the grounds in the Salford Quays. This wider vision includes homes and workspaces which will benefit the local community.The new stadium plans include a new public plaza which is reportedly 'twice the size of Trafalgar Square' and three 200m-high masts - described as 'the trident' - to support the lightweight roof.AdvertisementIt is not known how the football club, which announced another round of redundancies last month to 'return the club to profitability', plans to fund the project.
