Representatives of the American Football league have been in talks with London mayor Boris Johnson about a permanent tenancy, meaning the Hammers face more opposition.
Mayor of London Boris Johnson opened talks with American Football bosses when the St. Louis Rams and New England Patriots visited the capital for the league's annual fixture at Wembley Stadium last weekend.
"Given the ever-growing popularity of gridiron this side of the Atlantic the mayor and his team have held a number of meetings with senior executives in the last few days to explore further opportunities for NFL in London," a spokesman said. “The talks were exploratory, and we are at an early stage, but the signs are encouraging.”
Other interested parties for the stadium include League One club Leyton Orient, a football college and a consortium hoping to stage a Formula One grand prix in the Olympic Park; however, the NFL's proposition remains one of the frontrunners, as the stadium would only be required 10 times a year as opposed to more than 20 for domestic soccer.
"Sunday’s game at Wembley, in front of more than 80,000 fans, further cements London’s reputation as the natural home of American football outside of the US," the spokesman added. "Only last week the Mayor, in conjunction with the NFL, announced an expansion from one to two regular-season matches in London from 2013. That means in total an additional 44 million pounds in revenue for the capital from next year."
The Jacksonville Jaguars and Minnesota Vikings will each host games in London next season, with the Jaguars recently locking themselves into playing a regular-season game in London every season until 2016.
The news marks the latest setback for the Hammers' hopes of acquiring the stadium, after the Treasury refused to hand over 337 million pounds in Olympic contingency underspend to help install retractable seating.
