England's qualification for the 2014 World Cup rests on the results of two final home games with Montenegro, tonight, and Poland on Tuesday.
Roy Hodgson's side narrowly lead Group H and know two wins will secure a place at next summer's tournament - but both opponents are still able to qualify too.
Ukraine, who host neighbours Poland tonight, also stand well poised to leapfrog England should the unbeaten Three Lions drop points at home.
The result of the match in Kharkov will be known by around half-time in the match at Wembley, which kicks off at 8:00pm.
The task set for England in both the second half and on Tuesday's final night of qualifiers will then be known.
