The fourth matchday of the 2019-20 UEFA Champions League saw the likes of Paris Saint-Germain, Bayern Munich, and Juventus qualify for the round-of -16 with two games to spare, as 56 goals were scored on the matchday to take the season total to 207.
Galatasaray remains the only team in this season's competition not to have scored a goal and Real Madrid's young sensation Rodrygo scored the 96 hat-trick of the competition and the only one of Matchday-4.
Amidst a slew of record-breaking performances by players and teams, the following five stand out most
#1: Erling Braut Haland becomes the first player to score seven goals in his first four UEFA Champions League games
Erling Braut Haland has taken to the UEFA Champions League like a fish to water as the teenager scored in what was his fourth consecutive game in the competition to take his tally to seven so far.
Haland's goal in RB Salzburg's 1-1 draw at Napoli kept his club in the reckoning for a place in the round-of-16 while making the Norwegian only the fourth player in the competition history, to have scored in each of his first four appearances. The others are Ze Carlos (FC Porto), Alessandro Del Piero (Juventus) and Diego Costa (Atletico Madrid).
Haland is also the current top-scorer in this season's UEFA Champions League.
#2: Rodrygo becomes the third 18-year-old player to score a UEFA Champions League hat-trick
Real Madrid's Brazilian sensation Rodrygo became the second teenager this season and fifth overall, to score a UEFA Champions League hat-trick in his club's 6-0 thumping of Galatasaray.
The three-goal haul made Rodrygo only the second 18-year-old and the second-youngest player ever to score a hat-trick in the competition. Los Blancos legend Raul remains the youngest player to score three goals in a UEFA Champions League game when he netted thrice against Ferencvaros in the 1995-96 season.
Rodrygo's perfect hat-trick made him the 96th different player to score a UEFA Champions League hat-trick and the youngest Brazilian player to do so.
#3: Karim Benzema scores in 15th consecutive UEFA Champions League season
Karim Benzema became the first player since Lionel Messi to score in 15 consecutive UEFA Champions League campaigns when the Frenchman netted twice in Real Madrid's 6-0 win over Turkish side, Galatasaray.
Benzema scored his first goal in the competition for Olympique Lyonnais in a 2-1 win over Rosenborg in 2005-06, scoring a total of 12 goals in three seasons for the French club before moving to Real Madrid in the summer of 2008-09.
Benzema's 62 goals in the competition is the most ever by any player, after Cristiano Ronaldo (128) and Lionel Messi (113).
#4: Claudio Bravo becomes the first substitute goalkeeper to be sent off in the UEFA Champions League
Former Barcelona goalkeeper Claudio Bravo made an unwanted record in the UEFA Champions League, when he was sent off after coming on as a substitute to replace the injured Ederson against Atalanta. The Chilean became the first keeper to come from the bench and get his marching orders in the competition.
Bravo, who came on at half-time, rushed off his line and brought down the opposition winger Josip Ilicic, who was clean through on goal. For his moment of indiscretion, Bravo saw a straight red.
Defender Kyle Walker had to don the goalkeeping gloves for the remainder of the match, as Manchester City held on for a 1-1 draw at the home of the UEFA Champions League debutants.
#5: Chelsea produce comeback of the matchday against Ajax
Chelsea became the third English side in UEFA Champions League history to come from three goals behind to get a result and the first since Liverpool in the 2004-05 final against AC Milan.
The 2012 winners trailed 1-4 in the second half before scoring three goals to snatch an exhilirating 4-4 draw against nine-man Ajax. Earlier in the game, Chelsea conceded three goals in the first half of a UEFA Champions League game for the first time in their history.
During a nightmarish start to the game, Chelsea conceded two own goals in the first half, making them the first club since since CFR Cluj against Bayern Munich in October 2010, to concede two own goals in the first half of a UEFA Champions League game.
