Sir Jim Ratcliffe has been warned that redeveloping the area around Old Trafford could take up to 20 years amid his plans to revolutionise the stadium.
Ratcliffe wants to transform Manchester United's home into the 'Wembley of the North', boosting its capacity from around 74,000 to 90,000.
He desired public funding but Trafford Council have confirmed they will not give a penny towards the plans proposed by United's new minority owner.
Council bosses have welcomed his plans but warned a wider project will take up to two decades, as per The Times.
