The Arsenal midfielder has identified the trip to Podgorica as vital in the Three Lions' hopes of qualification for World Cup 2014 but hopes they treat it like any other match
Roy Hodgson's team hammered San Marino 8-0 on Friday night but remain two points behind the Group H leaders, who saw off Moldova, ahead of the Tuesday night clash.
Oxlade-Chamberlain admitted that the fixture at the Podgorica City Stadium looked vital but hoped England would approach it like any other game.
"It is the key game, definitely," he told Fifa's official website. "It is good to win every game but, with them being top of the group, it is even more important.
"You can't look too far into it because you then start getting distracted, and it puts added pressure onto you. We know what we've got to do, it's a pressure game but they are all pressure games for us."
The Arsenal youngster is anticipating a difficult atmosphere at the 12,000-capacity venue but believes his team-mates are seasoned enough to deal with any hostility.
"It will be hostile but if you look around this squad, the players have experienced hostile environments before at club and international level," Oxlade-Chamberlain insisted.
"It is a different challenge for us to overcome but, at the end of the day, it's a game of football and what goes on inside the white lines isn't to do with who is outside of them.
"We will speak about tactics before the game. If we can match them mentally and physically and approach the game in a right way, we've got a good chance."
