The win against the Spanish giants had also meant Liverpool would finish top of the group, having won all four of their games.
Therefore, it was a game that meant very little to The Reds.
Prior to the game, many assumed Klopp would field a weakened side, predominantly made up of academy players. However, the likes of Salah, Mane, Thiago, Joel Matip and Alisson Becker all started the match.
What followed was a really professional performance, highlighting the mentality of this squad, who managed to get the win even when the result didn't matter.
Tyler Morton was one of the academy players who did get an opportunity to start against Porto.
Morton made his debut at the earlier this season in the Carabao Cup against Norwich City. The 19-year-old impressed and kept his place against Preston North End before making his Premier League debut on Saturday.
As injuries hamper Liverpool's midfield, it was brilliant to see another academy prospect come in and look the part.
The defensive midfielder was solid throughout the match, looking very comfortable on the ball.
Morton had just two less touches and two less passes than his midfield partner Thiago.
He also played a key part in Salah's goal with a long ball into the Egyptian's path, before linking up with Jordan Henderson to score Liverpool's second.
Defensively, Morton was also very good, attempting more tackles than any other Liverpool player with five.
It was a crucial 90 minutes for Morton, who looks like another top prospect on Klopp's hands.
Alex Oxlade Chamberlain has now played more minutes in the last month, than he has in the previous 16 months combined.
The England International has been a key player over the past few weeks as injuries hit our midfield.
The Ox made an electric start to his Liverpool career in 2017, however he suffered a serious injury towards the end of the campaign and has struggled with injuries since.
This season however, the 28-year-old has so far put those injury woes behind him, making an appearance in each of Liverpool's last nine games.
The Ox played 82 minutes against Porto and completed the second most dribbles of any player on the pitch.
With Naby Keita, Curtis Jones and Harvey Elliot out with injuries, the Ox has had a real opportunity to prove his importance to the team. And with nine consecutive appearances, it's safe to say he has done.
Whether he can stay fit has been a question throughout his Liverpool career, but if he can then he will no doubt be a valuable asset to Klopp.
