#4: Lionel Messi becomes the first player in the Champions League to score against 34 different clubs
In his 700th competitive game for Barcelona (140 in the Champions League), Lionel Messi celebrated the landmark occasion with a record-breaking goal.
Messi scored Barcelona's second goal in his team's 3-1 home win over Borussia Dortmund. It made the diminutive Argentine the first player in the Champions League to score against 34 different clubs in the competition, breaking a tie with Cristiano Ronaldo and Raul (33 apiece).
The Argentina captain's nine goals in the competition against Arsenal is his highest against any club, while his 26 goals against English clubs is the most he has scored against clubs from any country.
#5: Erling Braut Haaland becomes the first teenager to score in each of his first 5 Champions league games
Erling Braut Haaland is one of 4 players (Ze Carlos, Alessandro Del Piero, and Diego Costa) to have scored in each of their first four games in the Champions League. The Norwegian teenager is also one of 3 players this season to have scored on each of the first four Matchdays of the competition.
When the substitute came on at Genk to score Salzburg's fourth of the night, Haaland became only the second player this season, the other being Robert Lewandowski, to score on each of the five Matchdays.
In the process, the Salzburg striker became the first teenager to score in each of his first 5 games in the Champions League, as his 8th of the campaign moved him within to within two goals of the season's top-scorer Lewandowski (10).
