Arsenal manager Mikel Arteta said Arsenal's season "is not good enough for this club" after defeat at Aston Villa confirmed their worst finish since 1995.
The Gunners can now finish no higher than eighth in the Premier League.
Arsenal qualified for the Champions League every season for 20 years under former manager Arsene Wenger but now must beat Chelsea in the FA Cup final to play in the Europa League next year.
They last played Champions League football in the 2016-17 season and will go into Sunday's final league game against Watford at least nine points short of the top four.
