• Ten sides secured qualification for the round of 32 on matchday five, making it 18 in total. With 17 clubs now eliminated, six places are left to be contested by 13 teams, with Group D the only one of the eight sections in which all four sides can still qualify. Not one of the eight clubs to be transferred over from the UEFA Champions League is yet known.
• The 18 qualified teams come from 14 member associations. Just three nations are assured of multiple representation in the round of 32 – Spain, with three sides (their full complement), and Italy and Russia, with two apiece. Austria, Belgium, Bulgaria, Denmark, England, France, Germany, Greece, Netherlands, Turkey and Ukraine all have one guaranteed representative.
• This number will definitely be increased to 15 nations as either Cyprus or Israel will take a team through. The maximum number of countries that could be involved in the round of 32 is 19, with possible qualifiers from Czech Republic, Slovenia and – via the UEFA Champions League – Portugal and Switzerland.
• Six of the 12 pools already have confirmed group winners – Valencia CF (Group A), PFC Ludogorets Razgrad (B), FC Rubin Kazan (D), Eintracht Frankfurt (F), KRC Genk (G) and Tottenham Hotspur FC (H). Three of these clubs have finished top of the pile before – Valencia in 2009/10, Rubin and Genk in 2012/13. Ludogorets and Eintracht have both achieved the feat on their competition debut.
• Tottenham are one of two sides with a 100% record in this season's group stage. FC Salzburg, in Group C, have also won all five of their matches and remain on course to become the first team to claim the maximum 18 points in a UEFA Europa League group for the second time, having become the first in the inaugural 2009/10 tournament. The only other clubs to have won all six group fixtures are FC Zenit (2010/11) and RSC Anderlecht (2011/12).
• Legia Warszawa suffered their fifth defeat out of five in Group J and remain not just without a point but also without a goal. Only Shamrock Rovers FC, in 2011/12, have previously lost all six group games, and no side has ever gone through the entire group stage without scoring. The record low is one goal, set jointly by PFC Levski Sofia (2009/10) and Salzburg (2010/11).
• Legia, FC Sheriff and R. Standard de Liège both endured a ninth successive UEFA Europa League match without a win, equalling the competition record held by three other teams – Salzburg, FC Steaua Bucureşti and PFC CSKA Sofia.
• Trabzonspor AŞ's 4-2 home victory against Apollon Limassol FC has made them this term's top-scoring club, with 13 goals – one more than Salzburg and Rubin. They will need to keep up their prolific run against Lazio on matchday six to equal the group phase record of 18 goals, owned jointly by Zenit, PFC CSKA Moskva and Anderlecht.
• Trabzonspor were spearheaded to that success over Apollon by a hat-trick from Olcan Adın, the 23rd treble in the competition. That enabled him to join Tottenham's Jermain Defoe as the UEFA Europa League's leading marksman in 2013/14 with five goals.
• The tournament's leakiest defence is that of FC St Gallen, who have conceded 13 goals in Group A. They will have to be in extremely charitable mood at home to Swansea City AFC on matchday six, however, to match Shamrock Rovers' record group stage tally of 19.
• PAOK FC extended their record sequence of away fixtures without defeat to nine (three more than any other side) with their 2-0 win at FC Shakhter Karagandy. The team from Kazakhstan are one of seven newcomers to the competition this season still awaiting a first victory, the others being Estoril Praia, HNK Rijeka, CS Pandurii Târgu Jiu, Tromsø IL, IF Elfsborg and FC Paços de Ferreira.
• Two debutant clubs did, however, gain their first three points on matchday five – FC Kuban Krasnodar and SC Freiburg – but there were first ever reverses for Swansea City, FC Slovan Liberec and Real Betis Balompié.
• PSV Eindhoven's Sweden forward Ola Toivonen played in the UEFA Europa League for the 35th time in the 2-0 loss at Ludogorets, thus moving ahead of Eduardo Salvio at the top of the competition's all-time appearance charts. Rubin's Israeli international Bebras Natcho is third on the list, two outings behind Toivonen.
