The England midfielder, 23, is in contention for a place against champions Chelsea at Wembley in what could be manager Arsene Wenger’s last game in charge of the Gunners.
Arsenal missed out on Champions League qualification for the first time in two decades and Oxlade-Chamberlain said: «The season has been an odd one. We finished on 75 points and in other years that might have left us in different situations.
«But times change and you have got to move forward with the other top teams. We failed to do that ultimately in the league this year, that’s why we missed out on the top four.
«It would be a bonus to finish on a more positive note but there will obviously always be that feeling that we wanted to finish higher up the league and there’s no doubting that.
«We can’t hide from that and we have to own up to it.»
Oxlade-Chamberlain is about to go into the final year of his contract and refused to answer questions about his future at a time when Liverpool, Everton and both Manchester clubs are all said to be interested.
It has been reported that Oxlade-Chamberlain is unhappy with the amount of first-team minutes he has been given by manager Wenger this season and the player did little to rectify such claims at a press conference at Arsenal’s training ground.
