New Manchester United co-owner Sir Jim Ratcliffe says his "preference" is to build a new stadium for the club that can also "serve the north of England".
United have played at the 74,310-capacity Old Trafford since 1910, but Ratcliffe acknowledged it had become "tired and in need of refurbishment".
A new stadium could be built next to the existing ground in Trafford Park.
"It's about time someone built a national stadium in the north of England," said the British billionaire.
Ratcliffe added the potential project could be a "catalyst for regeneration" in south Manchester and would therefore warrant a "conversation" with the government about using taxpayers' money.
