Borussia Dortmund have only won one of their six meetings with PSG in all competitions (D3 L2), beating them 2-1 in the first leg of the 2019-20 UEFA Champions League round of 16, before being eliminated 3-2 on aggregate.

Paris Saint-Germain have never won an away match against Borussia Dortmund, losing one and drawing two of their three visits, including a 1-1 draw in the group stages of this season’s UEFA Champions League. Indeed, this is the first time two teams have faced in the group stage and semi-finals in a single campaign in the competition since Real Madrid and Borussia Dortmund in 2012-13.

Borussia Dortmund are playing in the UEFA Champions League semi-finals for the fourth time; they’ve reached the final on two of the three previous occasions (1996-97 and 2012-13), with their only elimination at this stage coming in 1997-98 against Real Madrid.

This is Paris Saint-Germain’s fourth appearance in the UEFA Champions League semi-finals. They’ve lost all four games in their two previous two-legged ties (vs Milan in 1994-95 and Man City in 2020-21), although they did beat RB Leipzig in a single match in 2019-20.

Borussia Dortmund are unbeaten in their last 10 UEFA Champions League home games (W6 D4), their longest ever such run in the competition. Indeed, only three teams are on longer current unbeaten home runs in the competition: Manchester City (31), FC Bayern München (15) and Real Madrid (12).

Paris Saint-Germain have averaged 65% possession in the UEFA Champions League this season; their most in a single campaign on record (since 2003-04). Along with having more possession in all eight UEFA Champions League games under Luis Enrique, the French side have also allowed the fewest opposition passes per defensive action in the current tournament (8.7).

Borussia Dortmund’s per game average of 1.8 expected goals against is the highest of any team to progress from the UEFA Champions League group stages this season (18 xG against in 10 games). However, based on the quality of shots faced, Dortmund have conceded ten fewer goals than expected in the tournament this term (8 conceded from 18 xG against – excluding own goals).

Paris Saint-Germain’s Kylian Mbappé has scored eight goals in this season’s UEFA Champions League, his joint-best return in a single campaign (also 8 in 2020-21). The Frenchman is also just two goals away from becoming the ninth different player to score 50 UEFA Champions League goals – he’s scored a brace in his last two away games in the competition.

Marcel Sabitzer has assisted five goals in the UEFA Champions League this season, with two of those coming in their second leg victory over Atlético de Madrid. The only Borussia Dortmund player to make more assists in a single campaign in the competition is Ousmane Dembélé (6 in 2016-17), who now plays for opponents Paris Saint-Germain.

Vitinha has completed 96% of his passes under pressure in the UEFA Champions League knockout stages this season (212/222); the highest percentage of any midfielder (min. 10 such passes). The Portuguese also has the most line-breaking passes of any Paris Saint-Germain player in the knockout stages this term (45).
