Roy Hodgson's men need a draw to confirm their place in the quarter-finals, where they could face either Spain or Italy.
Walcott in particular will be hungry for his first start of the competition after a superb substitute's appearance against Sweden, where he scored one and assisted another to help England secure all three points.
Oxlade-Chamberlain won his fourth cap off the bench against the Swedes and will be looking to build on his start against France in England's opening match of the tournament.
