Since UEFA renamed its second tier UEFA Cup the Europa League in 2009, 23 clubs from outside the Premier League's Big 6 (Arsenal, Chelsea. Liverpool, Manchester City, Manchester United, Tottenham Hotspur) have qualified for the tournament.
Two of these clubs (Birmingham City and Wigan Athletic) qualified whilst being relegated, and of the remaining 21 clubs, on average the Premier League position has been 2.5 places lower the following season. Only two clubs have improved their Premier League placing from the previous season, and only one club which competed in the Group Stage.
In 2014-15, Southampton finished the Premier League season in 7th place and entered the Europa League in the Third Qualifying Round. After comfortably defeating Vitesse (Netherlands) 5:0 on aggregate to advance to the Play-Off Round, they were eliminated by Midtjylland (Denmark) 1:2 on aggregate.
The four additional games were completed by August 27th and Southampton went on to finish the 2015-16 Premier League season in 6th place, one place higher than the previous season and again qualifying for the Europa League.
The only time a non-Big 6 club has played in the Europa League Group Stage and improved its Premier League placing was in 2023-24 when West Ham United had placed 14th the previous season but had won the Europa Conference League to qualify.
West Ham entered the tournament at the Group Stage, playing six matches against Freiburg (Germany), Olympiacos (Greece) and TSC (Serbia) and advanced to the Round of 16 after winning the group with five wins and one loss.
West Ham again faced Freiburg winning 5:0 at home after losing 0:1 away, and lost in the Quarter-Final against Bayer Leverkusen (Germany) 1:3 on aggregate.
Despite playing these ten matches, West Ham were able to finish 9th in the Premier League, an improvement of five places.
Three clubs competed in the Europa League and finished in the same position as the previous season.
In 2009-10, Aston Villa were eliminated in the Play-Off Round after two matches.
In 2019-20, Wolverhampton Wanderers played 17 Europa League matches, losing to the eventual winners Sevilla in the Quarter-Finals, but were able to repeat their 7th place Premier League finish.
In 2020-21, Leicester City entered at the Group Stage and played eight matches before being eliminated in the Round of 32 by Slavia Prague (Czechia). They repeated their 5th place finish of the previous season in the Premier League.
Only two of 23 non-Big 6 clubs have played in the Europa League and finished higher in the PL than the previous season.
Southampton played 4 EL matches in 2015-16 and moved up one place to 6th while West Ham in 2023-24 played 10 EL matches finishing in 9th place in the PL, five places higher.
