Making his 700th competitive appearance for Barcelona, Lionel Messi set up Luiz Suarez at the half-hour mark to open the scoring against Matchday 5 visitors Borussia Dortmund.

Four minutes later, the Argentina captain doubled his team's lead. In the process, Messi broke a tie with Raul and Cristiano Ronaldo by scoring against a 34th different team in the UEFA Champions League.

Messi was far from done for the day though. The club-record scorer set up substitute Antoine Greizmann for his team's third goal. He then smacked the woodwork with a sublime free-kick as Barcelona's 3-1 win on the night sealed qualification for the knockout round as group-winners.

#1 Robert Lewandowski (Bayern Munich)

Robert Lewandowski

Robert Lewandowski has been on fire in European club football this season. After seeing his record 11-game scoring streak in the Bundesliga come to an end against Dusseldorf last weekend, the prolific Pole turned his attention to the Champions League as though he wanted to complete some unfinished business.

One of only three players to score on each of the first four Matchdays of this season's competition (the others being Erling Braut Haaland and Memphis Depay), Lewandowski became the first player to score on each of the five Matchdays when he scored Bayern's second of the night away at Crvena Zvezda.

Then in a devastating 14-minute blitz, Lewandowski scored thrice more, to score his first Champions League hat-trick in over four years (third overall). The Poland international also recorded the fastest quadruple in Champions League history.

It was Lewandowski's first four-goal haul in the competition since scoring all four for Borussia Dortmund in the first leg of the 2012-13 Champions League semi-final against Real Madrid.

In the process, Bayern's prolific marksman became the only player after Lionel Messi to score multiple four-goal hauls in a Champions League game. His efforts ensured the Bundesliga side sealed top spot in the group with a game to spare.
