The Spain international produced a composed performance alongside his fellow Liverpool defender as Jurgen Klopp’s side secured a 2-0 first-leg lead at Anfield last week.
Daniel Sturridge and Roberto Firmino scored either side of half-time in the last-16 clash against their bitter rivals to put Klopp’s men in pole position to reach the next round.
Moreno, who previously won the Europa League with Sevilla in 2014, made the most of his Monday night as he hung out with Portuguese midfielder Teixeira and England Under-21 starlet Ibe.
Moreno wrote on his Twitter page: “Friends😂😂 @Joao_Teixeira17 @IbeJordon ”
