Though Nyoni did not make it onto the pitch as the Reds returned to winning ways on Sunday, the 16-year-old was given an unforgettable experience.
Just months after swapping Leicester for Liverpool, and beginning his life in the U18s, the teenager was warming up with the likes of Mohamed Salah and Dominik Szoboszlai.
It was not his first taste of the senior setup, of course, with Nyoni having trained with Jurgen Klopps squad on a regular basis in recent weeks.
And speaking as part of LFCTVs pre-match coverage, academy player-coach Jay Spearing revealed the close attention Van Dijk is paying to the No. 98.
It was really nice going down to the AXA and being around and with him training with the first team, Spearing explained.
Virgil came out, he congratulated him on training with them, he said hes got a lot more to come and he really liked him.
Watching the U18s against Middlesbrough as well, Virgil came out to watch and see where Trey was playing he was playing with the U21s.
So to have the captain of Liverpool Football Club come to see where you are, how youre getting on, youve obviously caught the attention of the first-team players.
As long as he keeps his head down, he keeps going, hes got a really bright future.
Spearing who usually coaches with the U18s, but also plays with the U21s, and started alongside Nyoni in the recent 2-1 loss to League Two side Barrow in the EFL Trophy is well placed to comment on the youngsters situation.
Treys been fantastic since hes come in, he enthused.
With everything that was going on between the two clubs, he came into the club late.
Youre probably talking into August, maybe into September time, before he joined up with the lads.
But since hes come in, hes hit the ground running. Hes been a revelation.
His game understanding for such a young age is incredible. His weight of pass, everything about it. Hes a really talented boy.
Asked what stands out in particular about Nyoni, Spearing replied: His understanding of the game.
Weve given him a lot of responsibility when hes first come in. Even with him being 16, [at] U18 level he stands out.
He knows how the game should be played, he knows when to speed the game up, he knows when to slow the game down, what pockets and positions to pick up to cause the opposition problems.
Weve given him the license to just go and enjoy himself and play. For me, thats when Trey has been at his best.
Hes still got a long way to go, loads to improve, but hes started really, really well. Im absolutely delighted to see him involved with the first team.
