Sadio Mane scored a hat-trick as Liverpool thrashed Porto 5-0 to put themselves in complete control of their Champions League last-16 tie after the first leg in Portugal.

Mane broke the deadlock after 25 minutes in a hugely one-sided clash when his shot squirmed underneath Jose Sa.

Mohamed Salah's clever finish - his 30th goal of the season in all competitions - made it 2-0 shortly afterwards before Mane and Roberto Firmino both scored on the counter in the second half.

A resounding win was completed in the 85th minute when Mane drilled home to become only the fourth Liverpool player to score a hat-trick in the Champions League.

The return leg takes place at Anfield on March 6, but Liverpool's progress now looks a formality and they may even rest players ahead of their clash with Manchester United later that week.

Porto were unbeaten in their last 24 games in all competitions but they were no match for Liverpool, who seized control of the game with two goals in four minutes midway through the first half.
