Jim Ratcliffe, the billionaire co-owner of the soccer club, framed plans for the 100,000-seat venue as crucial to the British government’s plan to revive the northern English city.

LONDON — Manchester United unveiled plans on Tuesday to build the “world’s greatest” soccer stadium. A proposed 100,000-seater arena, costing around 2 billion pounds ($2.6 billion), would replace United's iconic Old Trafford home and surpass Wembley Stadium as the biggest in the United Kingdom.

Ratcliffe, who is one of Britain's richest people, said the new soccer venue could be a tourist attraction in the manner of the Eiffel Tower.
