The decision was made after a number of fact-finding missions to other stadiums including the Bernabeu and Nou Camp.
The cost of the project is expected to be a staggering £2billion.
A capacity of 100,000 is expected.
It is felt that a club of United’s standing should have a new state-of-the-art facility.
The new stadium will be built on land adjacent to the Red Devils' current home.
United are looking to not only build a stadium but regenerate the area of Trafford where the ground will stand.
They plan to KEEP Old Trafford rather than demolish it, and use it as a second venue.
They will scale it down to a 30,000-seater that can then be used for the women’s team and academy matches.
That would mean the history remains with statues and the Munich clock and memorial plaque all most likely staying in their current positions.
The club consulted with 30,000 fans about what to do and believe there is roughly a 50-50 split on staying or moving.
Old Trafford has been United’s home since 1910.
The target is for completion by 2030.
