The Gunners boast a faultless record of qualifying for the Champions League under Arsene Wenger.
He has, however, seen pressure mount this season as the north London outfit have faced fierce competition from their rivals – including their neighbours at White Hart Lane.
"Every game we try to give ourselves a chance," the experienced goalkeeper told BBC Sport following a 2-0 victory at St Mary’s on Wednesday.
"We shot ourselves in the foot against Tottenham and we are aware we need to win all the remaining games to be in the race.
"We had a big game against [Manchester] United (a 2-0 win) and then here, where historically we haven’t done that well in the league.
"It was tough in the first half but then we found the opening and deserved to win."
An impressive midweek win has lifted Arsenal back into fifth spot in the Premier League table and they are now just three points behind Manchester City, and four adrift of Liverpool with three games remaining.
