The Football Association's decision to offer full refunds to supporters who decide it is not worth the hassle of getting to Wednesday night's World Cup qualifier at Wembley could cost them in excess of £1million.
Although there was no legal requirement to offer fans their money back following the start of a 48-hour London Underground strike, the FA felt it necessary to at least make the gesture given the difficulty in getting to a venue that urges people to attend by using public transport.
And the final bill could turn out to be well into seven figures as a previously anticipated 70,000 crowd decides whether to make the journey or not.
It was certainly a test for new FA chief executive Ian Watmore, who only took up his post on June 1.
Watmore had meetings with the Metropolitan Police, Brent Council and London transport authorities yesterday morning and emerged believing he had done the best thing for all concerned.
Turnstiles will be open two-and-a-half hours before kick-off at 5.45pm, with car parks being available in advance of that.
''Travelling will not be straightforward and fans should prepare to have a disrupted journey,'' said Watmore, who confirmed later that nearby Wembley overground stations would be used.
''Supporters should not rely on public transport and refunds will be made available to all ticket holders who decide not to attend this game.
''We are disappointed this has happened. But we know English people love their football and will turn out in force I am sure.''
