Beaten 2-0 at RB Leipzig on matchday three, Celtic host the German club in Glasgow knowing that they can ill afford another defeat if they are to keep alive their hopes of qualifying from UEFA Europa League Group B.
• Both clubs had recorded a victory against Rosenborg and a defeat against Salzburg prior to their first head-to-head in Germany – a match settled in the home side's favour by goals from Brazilian striker Matheus Cunha and Portuguese winger Bruma.
• If Leipzig complete the double over Celtic, they would be through to the round of 32 should Rosenborg fail to beat leaders Salzburg in the other Group B encounter. Celtic will be out if they lose and Salzburg avoid defeat.
• The two teams had never met in UEFA competition prior to matchday three, when Leipzig faced Scottish opponents for the first time.
• Celtic have won only three of their 23 matches against German opposition (D5 L15) and none of the last ten (D3 L7). Furthermore, they have lost six of 11 at home including each of the last three. Their last victory was 3-1 against VfB Stuttgart in the fourth round of the 2002/03 UEFA Cup.
• Celtic won the Scottish treble of Premiership, Scottish Cup and League Cup for the second successive season in 2017/18, but they were unable to secure a hat-trick of UEFA Champions League group stage appearances this term, their elimination of Rosenborg followed by defeat to AEK Athens. A 4-1 aggregate victory over Lithuanian champions Sūduva in the UEFA Europa League play-offs maintained Celtic's post-summer interest in Europe.
• This is Celtic's fifth season in the UEFA Europa League group stage. Three of their four previous campaigns have ended in elimination, the exception 2014/15, when they reached the round of 32. They also got to that stage of the competition last season after finishing third in their UEFA Champions League group, but lost to Zenit.
• The Glasgow club are unbeaten in continental contests at Celtic Park in 2018 (W5 D1), their matchday one victory over Rosenborg (1-0) ending a ten-match winless run in European group stage fixtures (D2 L8).
• Leipzig finished sixth in the 2017/18 Bundesliga to make it two European qualifications in a row, their debut continental campaign having ended in the UEFA Europa League quarter-finals – eliminated by Marseille – after they finished third in their UEFA Champions League group.
• Having defeated Häcken of Sweden and Romania's Universitatea Craiova in the first two qualifying rounds this season, Leipzig needed a last-gasp penalty from Emil Forsberg to win their play-off 3-2 on aggregate against Ukrainian club Zorya Luhansk.
• Leipzig are unbeaten away from home in Europe this term, their 3-1 win at Rosenborg on matchday two following three successive draws in the UEFA Europa League qualifying phase. Their away record in two seasons of European competition is W3 D4 L3.
