Paris Saint-Germain have been imperious so far in Group B, and will look to wrap up first place when eliminated Celtic FC come to the Parc des Princes.
• Unai Emery's team have maximum points after four games and are through to the last 16. They will clinch top spot if they win and second-placed FC Bayern München do not pick up three points at bottom side RSC Anderlecht – or if Paris draw and Bayern lose.
• Celtic suffered their biggest European home defeat against Paris on matchday one, going down 5-0 in Glasgow. The Scots cannot finish in the top two but will seal third position if they win and Anderlecht do not, or if they draw and Anderlecht lose.
• The teams' only previous encounters came in the 1995/96 UEFA Cup Winners' Cup second round, Paris running out comfortable 4-0 winners over the two legs – and going on to lift their sole piece of major European silverware.
• The French side were 1-0 first-leg victors at the Parc des Princes thanks to a Youri Djorkaeff goal (76) before Patrice Loko struck twice in Glasgow (36, 42) with Pascal Nouma (68) getting the other.
• Paris have scored 17 goals in winning their first four matches, conceding none. No team have ever gone through a UEFA Champions League group stage without conceding.
• Paris are unbeaten in their seven fixtures against Scottish clubs (W4 D3); at home their record is W2 D1.
• Paris have lost just one of their last 45 European home games since crashing 4-2 to Hapoel Tel-Aviv FC in the 2006/07 UEFA Cup group stage (W29 D15) – going down 3-1 to FC Barcelona in the 2014/15 quarter-finals.
• They picked up five points at home in last season's group stage (W1 D2).
• Quarter-finalists in four successive seasons between 2013 and 2016, Paris were on the wrong end of the biggest comeback in UEFA Champions League history in last term's round of 16. Having won 4-0 at home to Barcelona, PSG succumbed 6-1 in the away leg to bow out with Neymar – now of Paris – providing two goals and an assist.
• Celtic are without a win in their last six visits to France (D2 L4). Their sole success came on their first trip, a 3-1 win at FC Nantes in the second round first leg of their victorious 1966/67 European Cup campaign.
• Celtic's overall record against French clubs is W5 D2 L8.
• Prior to matchday one, the Scottish side's last experience of French opposition came in the form of Stade Rennais FC in the 2011/12 UEFA Europa League group stage. Celtic won 3-1 at home after a 1-1 draw in France.
• The Hoops have won just one of their last 19 group stage fixtures in the UEFA Champions League or UEFA Europa League (D7 L11), beating Anderlecht 3-0 in Belgium on matchday two. That ended a ten-game (D3 L7), four-year winless run in the UEFA Champions League group stage; their previous victory had been a 2-1 home success over AFC Ajax on 22 October 2013.
• In 2016/17 Celtic came fourth in their section, taking three points from six matches. They suffered a record 7-0 loss at FC Barcelona but drew 1-1 at both VfL Borussia Mönchengladbach and Manchester City FC.
• Celtic began the season in the second qualifying round, beating Linfield FC (2-0 away, 4-0 home) and then Rosenborg BK in the third qualifying round (0-0 home, 1-0 away). They posted a fifth straight clean sheet with a 5-0 win against FC Astana in the home first leg of their play-off, advancing despite a 4-3 loss in Kazakhstan which ended a four-game (W2 D2) unbeaten away run in Europe.
• The victory at Linfield broke Celtic's 11-match sequence without an away win in Europe (D6 L5).
• Scottish champions for a sixth consecutive campaign in 2016/17 – when they went through their domestic season unbeaten – Celtic are in the group stage for the tenth time.
