Manchester United have hired Architects Populous and management consultants Legends International to work together on plans for an Old Trafford redevlopment.
Both companies collaborated over the plans for the 63,000 seater Tottenham Hotspur Stadium back in 2019.
Old Trafford's renovations are designed to expand the capacity even further, despite it being the largest club venue in the nation already with 74,000 seats.
A statement on United's website read: "Work will begin immediately on developing options for Old Trafford and studying their feasibility, with the aim of significantly enhancing the fan experience.
"Fans will be at the heart of the process, starting with a meeting between the consultants and the Manchester United Fans' Advisory Board later this month."
It was first believed that the club was considering building an entirely new stadium, a concept that received support from former Red Devil and pundit Gary Neville.
However, with the plans now being greenlighted for renovations, it seems all plans for a new stadium have been scrapped.
The venue is now 112 years old, and despite three sides of the stadium being renovated in the last three decades, there's still major problems around the ground, including major leaks from the south stand.
The club are also exploring options to improve their training ground, with KSS appointed to develop plans for an "expanded, state-of-the-art facility for the men's, women's and academy teams".
