Roberto Firmino has been delighting Liverpool fans with his performances this season.Having been converted to a striker from an attacking midfield role, the Brazilian had scored seven goals and made four assists in his 16 games so far this campaign, therefore being directly involved in almost a goal every game.While he isn't the most prolific front man in the Premier League, his hard-working attitude and skill on the ball makes him stand out to the Reds' supporters.He has also formed a part of what the media have dubbed the 'fab four', alongside Philippe Coutinho, Mohamed Salah and Sadio Mane.And Firmino was involved again when Liverpool visited the London Stadium to face West Ham.After taking a 2-0 lead in the first-half thanks to Salah and Joel Matip, the Merseysiders were pegged back by Manuel Lanzini's deft finish ten minutes into the second period.However, Firmino's brilliance allowed Liverpool to quickly double their advantage again, just 57 seconds after Mignolet was picking the ball out of his net.He turned Winston Reid inside-out on the halfway line, leaving the Kiwi mesmerised, and fed Alex Oxlade-Chamberlain who got his first Premier League goal for the Reds at the second time of asking, with Joe Hart saving his initial effort.Salah would go on to add his second and the visitors' fourth shortly after to complete the rout, as Liverpool won by a three-goal margin for the third time in seven days.Firmino, though, was cruelly denied his fifth assist of the campaign, with Hart's initial intervention meaning there was no official credit given to him for Oxlade-Chamberlain's goal.

Twitter was in awe of the skill though, with his touch receiving praise from fans of all clubs.

Unfortunately rules are rules, and Oxlade-Chamberlain's inability to finish first time cost many of Firmino's backers a vital three points.

Liverpool, on the other hand, had them wrapped up with the goal.
