UEFA Champions League round of 16: 5 things we learned from the first leg matches

#2 Liverpool are the dark horses of the tournament

Liverpool routed Porto away from home

Just how often have Liverpool scored four or five goals past an opposition this season? Many times. But when they did the same against a Porto side whom they had never beaten at the Dragao and who were also unbeaten in the Primeira Liga this season, it was special.

The regular men were in charge of the demolition as Mohammed Salah, Roberto Firmino, and Sadio Mane all netted goals to ensure the fall of the Dragões. It was not all about the goals either. Liverpool managed to keep a clean sheet - a rare feat for the Reds - at the Dragao where Porto have averaged nearly three goals per game.

Liverpool are one of the only three teams to remain unbeaten in the Champions League so far, the other two sides being Barcelona and Tottenham. Liverpool have also scored the most number of goals this season with 28 followed by PSG who have netted a total 26 times.

Given the blistering form of Salah and Firmino, the Merseysiders are a threat to any opposition. With Liverpool competing only in the Premier League apart from the Champions League, where the hopes of a title run are fairly slim, Jurgen Klopp may shift his focus towards securing European glory.

Liverpool have a more than capable side of going all the way in this year's Champions League and if their recent performances are anything to go by, a sixth European crown may well be on its way to Anfield.
