Liverpool v Dortmund background

The 'Jürgen Klopp derby' concludes at Anfield, with the manager's current club Liverpool FC eager to finish off his old side Borussia Dortmund in the UEFA Europa League quarter-finals.

Previous meetings
• Divock Origi gave the Reds the lead in the first leg in Dortmund, but Mats Hummels evened things up after the break.

• The teams have now met four times in UEFA competition, with the record W1 D2 L1. Most notably, Willi Multhaup's Dortmund beat Bill Shankly's Liverpool 2-1 after extra time in the 1966 European Cup Winners' Cup final in Glasgow.

• In the 2001/02 UEFA Champions League first group stage, Gérard Houllier's Liverpool drew 0-0 with Matthias Sammer's Dortmund in Germany then won the return match 2-0 – with Phil Thompson in charge of the Reds while Houllier recuperated following heart surgery.

• Liverpool are unbeaten in 15 UEFA home games against German sides (W12 D3). Their record in 35 fixtures against German opposition reads W16 D13 L6. They landed their first European trophy by beating VfL Borussia Mönchengladbach in the 1973 UEFA Cup final and overcame the same team in the 1977 European Champion Clubs' Cup decider.

• Dortmund's overall record in 22 competitive outings against English opponents is W11 D5 L6 (W6 D4 L1 in Dortmund – W4 D1 L5 in England). They eliminated Tottenham Hotspur FC with back-to-back victories in this season's round of 16.

Form guide
• Liverpool are unbeaten in seven European home matches – four wins (only one of them by a margin of more than one goal) and three 1-1 draws, which suggests a tense night in prospect against Dortmund.

• Liverpool are the only club to make it from the start of the group stage to matchday 11 unbeaten, with four victories and seven draws – more than any other side in the 2015/16 tournament. No team has gone 12 games unbeaten in a single UEFA Europa League campaign, group stage to final, though Club Atlético de Madrid went 15 matches without defeat across two editions of the UEFA Europa League, from November 2011 to October 2012.

• Dortmund have won five of their seven European away fixtures this term (W5 D1 L1). They have not been held to a 0-0 draw in their last 37 UEFA games.

• Dortmund have won seven of their ten matches since the start of the group stage; only Villarreal CF have won as many.

• Liverpool lost to Beşiktaş JK on penalties in last year's round of 32 and to FC Zenit at the same stage of their previous UEFA Europa League adventure, in 2012/13. The 1973, 1976 and 2001 UEFA Cup winners last got to the quarter-finals in 2009/10, ousting SL Benfica en route to a semi-final loss to Atlético Madrid.

• Prior to this campaign, Dortmund had not featured in the UEFA Europa League since an unsuccessful group stage foray in 2010/11. They were twice losing UEFA Cup finalists, succumbing to Juventus in 1993 and Feyenoord in 2002.
