• The UEFA Europa League round of 16 first legs brought three home wins, three away victories and two draws. Of the 18 goals scored – eight more than at the same stage last season – ten came from the visiting side. Indeed half of the eight registered by the home teams were scored by one club, Olympique Lyonnais.
• SL Benfica, who have been in more UEFA Europa League quarter-finals than any other side, look likely to increase their tally to four participations after triumphing 3-1 away to Tottenham Hotspur FC. Valencia CF are set to match Benfica's current record of three appearances after winning 3-0 at PFC Ludogorets Razgrad.
• The game at White Hart Lane was Benfica's record 25th in the UEFA Europa League knockout phase, seven more than the next highest team in the list, Club Atlético de Madrid.
• It was also the Portuguese club's 22nd victory in the competition, just one behind Atlético's record mark, and the three goals they notched against Tottenham lifted their all-time tally to 61, level with Atlético in joint-second place behind top-scoring PSV Eindhoven (64).
• Ludogorets's home defeat by Valencia ended the Bulgarian side's unbeaten run in the competition, which lasted eight matches. However, fellow debutants ACF Fiorentina scored a late equaliser at Juventus to stretch their sequence of UEFA Europa League fixtures without defeat to nine. The Viola remain the only one of the competition's 156 participating clubs never to have lost a game.
• FC Salzburg failed to maintain their 100% record in this season's tournament, drawing 0-0 at FC Basel 1893, but they are still one of four group stage survivors unbeaten after nine matches this term, the others being Fiorentina, AZ Alkmaar and Lyon. In addition, four sides that joined the competition mid-term from the UEFA Champions League are still undefeated after three outings – Juventus, Benfica, Basel and FC Porto.
• Of the 16 teams still participating in the UEFA Europa League, just seven actually began their European campaign in the competition. The longest survivors are Sevilla FC, who started in the third qualifying round. Four others embarked at the play-off stage – Tottenham, AZ, Fiorentina and Real Betis Balompié – while two more entered in the group phase, FC Anji Makhachkala and Valencia.
• Ludogorets and FC Viktoria Plzeň both kicked off their European campaigns in the second qualifying round of the UEFA Champions League and, with 15 matches now completed, have therefore played more European games in 2013/14 than any other club.
• Valencia's success at Ludogorets maintained their perfect record away from home in this season's edition and stretched their overall streak to five wins out of five on the road – one short of the UEFA Europa League record jointly held by Atlético and Porto.
• Valencia also claimed an unwanted record in Bulgaria by collecting their eighth red card in the UEFA Europa League. Two other sides, FC Steaua Bucureşti and Sporting Clube de Portugal, have also had eight players sent off, but the Spanish team's dismissals have come in fewer games (29, as opposed to 30 and 38 respectively).
