Manchester United have been warned a plan to demolish and rebuild Old Trafford will cost up to £1.5billion.
United officials have been advised that drastic plans to build a state-of-the-art stadium on land adjacent to Old Trafford would make it the most expensive ever built in the country.
The cost of a new 80,000-capacity stadium is expected to exceed Tottenham's £1.1billion state-of-the-art home, according to external consultants.
Prices of steel and essential materials have increased sharply since Tottenham completed their ground, while the conflict in the Ukraine is creating uncertainties and price hikes for major construction projects.
