With the conclusion of the sixth Matchday of this season's Champions League, the group-stage of the competition has drawn to a close.
The 2019-20 UEFA Champions League has produced the most group-stage goals (308) since the Round of 16 was introduced in 2003-04, eclipsing the previous mark of 306 set two seasons ago.
11 teams had already qualified for the knockout round before the sixth Matchday, leaving 8 teams in contention for the 5 remaining berths. On Matchday 6, Liverpool won 2-0 at Salzburg, Chelsea beat Lille 2-1 and Valencia won 1-0 at Ajax to book their knockout round places before Atalanta won 3-0 at Shakhtar Donetsk and Atletico Madrid beat Lokomotiv Moscow 2-0 at home to complete the Round of 16 line-up.
Let us now have a look at 5 interesting stats from Matchday 6 of the 2019-20 UEFA Champions League:
#1 Bayern Munich record best goal difference among all teams in history with 100% group stage success rate
Already qualified Bayern Munich completed their group-stage engagements with a perfect 6/6 record, becoming only the 6th team and the first since Real Madrid in 2014-15 to win all their 6 group-stage games in the UEFA Champions League.
In the process, the Bavarian giants produced the best goal difference of '+19' by a group winner in the history of the competition.
Bayern's 24 goals is the most scored by any of the 32 teams in the group-stage of this season's competition, ahead of Tottenham Hotspur (18) and Paris St. Germain (17).

#2 Atalanta become the first team to qualify for the knockout round after losing their first three games
The only tournament debutants in this season's Champions League, Atalanta, created history on Matchday 6 by becoming the first team to qualify for the knockout round of the competition after losing their first three games.
After scoring just twice and conceding 11 goals in defeats to Dinamo Zagreb (4-0 away), Shakhtar Donetsk (1-2 home) and Manchester City (5-1 away) in their first three games, Atalanta conceded just one goal in their next three.
A 1-1 home draw with group-winners Manchester City followed by a 2-0 home win over Dinamo Zagreb and a 3-0 win at Shakhtar Donetsk confirmed Champions League action beyond Christmas for the competition debutants.
#3 Ansu Fati becomes the youngest scorer in a Champions League game
Barcelona's teenage sensation Ansu Fati created Champions League history on Matchday 6. His late winner at Internazionale on Matchday 6 made the 17 year, 40 day old winger the youngest-ever scorer in the competition (group-stage to final).
In the process, Fati broke the 22-year record held by Ghana's Peter Ofori-Quaye, who at 17 years 195 days had become the youngest scorer in the Champions League. Ofori-Quaye had scored in Olympiacos's 5-1 home win over Rosenborg in a group-stage game in the 1997-98 edition of the competition.

Polish striker Arkadiuz Milik netted a hat-trick as already-qualified Napoli beat Genk 4-0 at home to complete their group-stage engagements on a winning note.
It was the 8th hat-trick in this season of the Champions League, and Milik became only the third player to score a first-half hat-trick for an Italian side in the competition - emulating Simone Inzaghi (Lazio) and Marco Simone (AC Milan).
#5 Neymar has scored and assisted in a Champions League game on 9 occasions
Brazilian striker Neymar scored a goal and provided an assist to a teammate as group-winners Paris St. Germain overwhelmed Galatasaray 5-0 at home to complete their group-stage campaign with 5 wins and a draw.
Neymar pulled off this double in a Champions League game for the 9th time in his career since his competition debut in 2013.
During this period, only Cristiano Ronaldo (11) and Lionel Messi (10) have done so on more occasions than the Brazilian striker. Incidentally, Ronaldo and Messi are the two all-time top-scorers in the history of the UEFA Champions League.
