Defender Virgil van Dijk is excited by how Liverpool's new-look forward line has already provided a glimpse of the future.Cody Gakpo, the club's £37million January signing, and Darwin Nunez, who arrived in the summer, both scored twice in the 7-0 trouncing of Manchester United before Mohamed Salah could complete his record-breaking double.It may only be one game but three Liverpool players scoring at least two apiece against United for the first time since 1908 was not the most significant feature of a remarkable evening at Anfield.With Roberto Firmino, the other goalscorer, announcing his decision to leave in the summer when his contract ends, only Salah remains from the famed frontline which terrorised defences across Europe for several seasons.However, the rebuild is already well under way with Nunez, who could become a club record #85m signing if all his add-ons are paid to Benfica, starting to make the left-sided role previously owned by the now-departed Sadio Mane his own with 14 goals this term.Gakpo, who had been a United target only for Liverpool to swoop in, has had less time to adapt but has now scored in three of his last four starts and looks set to assume Firmino's central position."Very clinical.
I think a lot of those goals were world class in my opinion," Van Dijk said."The first one, I think the whole build-up towards it was outstanding.
Obviously (Gakpo) cutting in to his right foot, a quality finish."Obviously it's been a difficult time to come in any club, I think, in the winter for any player but he's settling in very well.
It's a very difficult position to play."Obviously he learns from one of the best, I think, each and every day with Bobby Firmino.
