Borussia Dortmund secured a spot in the Champions League quarter-finals for the second consecutive year by overcoming Lille 2-1 in the second leg, achieving a 3-2 aggregate win. The teams were tied after a 1-1 draw in Dortmund last week. Jonathan David gave Lille an early lead, slipping a shot past Gregor Kobel, who could have done better.Dortmund responded with determination, nearly equalising during a chaotic goal-mouth scramble. Pascal Gross's header narrowly missed the target just before halftime. After the break, Niko Kovac's team showed renewed energy and levelled the score in the 54th minute. Emre Can calmly converted a penalty following Thomas Meunier's foul on Julian Brandt.Beier then secured victory for Dortmund with a remarkable strike into the top corner after Karim Adeyemi hit the crossbar. David had one final opportunity to equalise for Lille but his volley went straight to Kobel, ending Lille's hopes of reaching their first-ever quarter-final in this competition.Dortmund will now face Barcelona in the semi-finals. Despite Lille's exit, they had notable wins over Real Madrid and Atletico Madrid to qualify directly from the league phase by finishing in the top eight. This marked a disappointing end for them.Dortmund has reached the Champions League quarter-finals nine times and achieved this milestone consecutively for the first time since 2013-14. Beier scored his first Champions League goal, while Can's penalty was crucial. Can has successfully converted all 12 penalties he's taken across competitions, with five this season alone.Serhou Guirassy assisted Beier's goal, bringing his tally to 14 goal involvements (10 goals, four assists) in this Champions League season. This equals Mohamed Salah's record for most goal involvements by an African player in a single campaign set in 2017-18.
