NFL matches will take precedence over England internationals at Wembley after the Football Association stunned the game by negotiating a shock deal to sell the national stadium to American billionaire Shahid Khan for around £600 million.

The move – which has been questioned by the Department for Digital, Culture, Media and Sport – is on the verge of being agreed and will have huge implications for football with:

The FA pledging to invest all profits from the sale into grass-roots football.

England forced to play internationals away from Wembley in October and November, with Khan’s Jacksonville Jaguars NFL side to become primary tenants.

FA Cup semi-finals potentially being played elsewhere, although the final will remain at Wembley.

The FA retaining the value of the Club Wembley business in perpetuity, which is estimated at being worth around £350 million.

The FA sees the sale as a chance to free itself of the most financially onerous parts of owning Wembley. Khan, who owns Fulham, said last night that he would commit to investing in the stadium, which, although leased by Tottenham this season, is used relatively little. He believed the deal could be finalised by August.

The governing body is thought to be concerned that in the long-term the new Wembley, opened in 2007 and a commercial success, will have to be significantly refurbished and rebuilt.
