Roberto Firmino has become quite the cult hero at Liverpool.
The Brazilian attacker has become arguably the most crucial cog in Jurgen Klopp's well-oiled attacking machine.
Firmino's pressing and ability to bring both Mohamed Salah and Sadio Mane into the game has been vital in Liverpool's improvement in recent seasons.
When he was bought from Hoffenheim in the summer of 2015 for around £29m, there was a lot of optimism surrounding his arrival.
He was one of the stars of the Bundesliga, but initially struggled under Brendan Rodgers.
But he's gone from strength to strength under Klopp, with 2017/18 his finest goal scoring season to date - he notched 15 Premier League goals and 10 in the Champions League.
So how did Liverpool spot such a talent? Well, a video has emerged on YouTube titled 'The match that made Liverpool buy Roberto Firmino'.
It was actually the Brazilian's last game for Hoffenheim and his performance against Hertha Berlin secured Europa League qualification.
He scored the winner and was named man of the match. You can watch his highlights below.
His assist for Anthony Modeste's goal in the eighth minute is simply sublime, nutmegging a defender and then chipping a perfect ball over the Hertha defence.
Roy Beerens would equalise in the 72nd minute, but Firmino was on hand to score the winner from a tight angle just eight minutes later.
His touch, speed, dribbling and passing ability are all on show in a wonderful performance.
Firmino was actually playing in a number 10 role for Hoffenheim, with Klopp the man deciding to turn him into the a centre-forward.
The Brazilian has struggled for goals this season, netting just twice in 11 Premier League appearances.
However, he has been on target twice in the Champions League as well, with his selfless performances still hugely benefiting the team.
