I agree, players like Nunez need time to adapt to a new league as competitive as the EPL and we sure knows he has potential, So all Liverpool needs is patience for him to get to that top tier they expect!!!
Over time Nunez will also get used to the team and the environment in which he plays, because adaptation is only a matter of time which eventually will also get used to everyone who has been in a new environment and I don't think there is much to talk about Nunez at that time this is because the final hope of the team that is currently sheltering him is to be even better next season by scoring more goals and glorious achievements.
His first season was terrible and the second season if he dosent play good and show the results i think he wont get any more chances in the club. This isnt the Portugal league where only 3-4 teams dominate over the others. Here even when you play against the last team in the league its hard to score. So he needs to get serious and start scoring from those easy chances.
