Burnham has expressed support for the plans to revitalize the stadium with a "mixed-use" neighborhood that includes apartment buildings, shopping centers, and new public transportation hubs.
Global advisory firm Oxford Economics revealed the regeneration project could deliver 92,000 new jobs, more than 17,000 new homes and an extra 1.8million visitors per year to the area.
"This could be the biggest regeneration scheme I've ever seen in this country," said Burnham.
"We hope it's the best football stadium in the world, which brings benefits to residents around it."
The project is being spearheaded by United co-owner, British billionaire Jim Ratcliffe, who bought a minority stake in the club earlier this year.
Although Ratcliffe initially hinted he could pursue government assistance in order to fund a "Wembley of the north", that appears now to have been ruled out.
