Raphinha equalled Lionel Messi for the most goal involvements by a Barcelona player in a single Champions League season.

In Wednesday's other quarterfinal first leg, Paris Saint-Germain overcame a 1-0 deficit to English Premier League club Aston Villa at the Parc des Princes en route to a 2-1 victory. The decisive rematches will be played next week in Dortmund and Birmingham, respectively. Here are three quick takeaways following Wednesday's games.

Barcelona won their UEFA Champions League group match 3-2 away at Dortmund’s BVB Stadion in December in what could best be described as a topsy-turvy encounter. In a far-from-convincing victory, Barcelona twice gained a lead on the scoreboard, only for forward Serhou Guirassyas to equalise twice for Dortmund.
