On the lookout for an unprecedented third successive UEFA Europa League triumph, Sevilla FC can feel confident as they welcome final hosts FC Basel 1893 with the scores still square at 0-0.
• The clubs drew 0-0 in Basel in the first leg in what was their first European encounter.
• Sevilla's only previous match against Swiss opponents in Europe produced a 4-0 victory at Grasshopper Club Zürich in the UEFA Cup group stage in November 2006.
• Basel's record in 17 games against Spanish sides is now W2 D5 L10 (W2 D3 L4 in Basel – W0 D2 L6 in Spain). Those away fixtures include a number of heavy defeats – seven goals scored, 24 conceded. Basel conceded five in each of their last two games in Spain – 5-0 at Valencia CF and 5-1 at Real Madrid CF, both games played in 2014.
• Sevilla have won their last two European home games without conceding, and have prevailed in their last ten home fixtures in this competition. An eleventh successive UEFA Europa League home win would be a competition record.
• Basel have lost only once in six UEFA games on the road this season, that run including four wins and a scoring draw – all results which would be good enough to eliminate Sevilla.
• Sevilla won the UEFA Cup/UEFA Europa League for a record fourth time last term. No team have won three consecutive editions of a UEFA competition since FC Bayern München's third straight European Champion Clubs' Cup triumph in 1975/76. Sevilla are the first club to contest the UEFA Europa League round of 16 for three seasons running.
• Basel most recently played in the round of 16 in 2013/14, when they battled through to the last eight. Their best campaign in this competition came in 2012/13 when they progressed to the semi-finals, falling to eventual winners Chelsea FC.
