True, but 2 -3 years is too long. Maybe Klopp can add him as a loan player if he wants to keep him. That was because Nunez was only 23 years old, there was still a chance he could get better. This situation is certainly detrimental to Liverpool because Nunez's transfer is quite expensive.
Nunez's performance at the World Cup was also bad, in fact they had to go home immediately because they didn't qualify for the group phase. But looking at the world cup, Nunez played a lot wide to support Suarez and Cavani.
This can be honed again by Klopp as a coach to improve Nunez's performance on the field with Liverpool but if he is loaned to me it is not quite right even though it is still easy for Nunez at least he is still needed for Liverpool at the moment and indeed what we have seen Nunez has not shown anything what Mane wants, but when he was still at Bengica Nunez was quite good, it's just that he might need to adapt for a long time.
It's like that, Nunez and the national team can't perform well, just mediocre, this is almost the same as Liverpool and obviously the game is very different from Firmino or Mohamed Salah.
There were several factors that became Nunez obstacles at Liverpool, one of which was based on rumors that Nunez didn't really understand English. Therefore, in several matches at Liverpool, Nunez deliberately brought translators so that what Klopp said could be understood. This may be trivial, but in terms of clear communication, it will greatly affect the synchronization of thoughts between coaches who implement strategies and players who implement them on the field. Nunez has plenty of time to learn how to communicate, let alone language problems.
