The EPL is tougher than other leagues, including the portuguese league. There are not many players who can adapt quickly. Nunez also included, he needs more playing time for adjustments. But it's a pity that he has already got a red card, for poking the crystal palace defender.
It seemed to be a small mistake that made him miss 3 games.
Premier League is a bigger one than Portuguese League but Nunez can succeed there. He has enough good skills to succeed and his body is great and fitted with Premier League.
The red card is a big lesson for him but only Nunez can learn and improve. Fortunately he has a good coach to teach him. The reaction of Klopp after the red card is a terrible and strong warning for Nunez. He must change himself if he want to have a future in Liverpool. Klopp will not keep that mistake in his mind but he will seriously force Nunez to change.
You didn't understand what I mean. Nunez was brought in as a replacement for Sadio Mane. Now if Nunez is not able to fill Sadio Mane's void then Liverpool's performance will not stabilize. A good performance from Nunez is essential for Liverpool to be stable. Liverpool also has some problems in midfield and defense. It is hoped that once the injured players return to the squad, Liverpool will be able to perform well again.
Nunez can replace either Mane or Salah but he needs time to adapt to new league, new club. With skills Nunez has, I think he can play good in Premier League but he must avoid doing stupid reactions like what he did recently. He should learn Mane, Firmino, Salah, not learn bad emotional reactions like Luiz Suarez.
