I think Liverpool are in a transition period and they've actually been pretty good so far. After being left by Firmino who joined the Saudi league team, Darwin Nunez will now become the successor of the number 9 jersey at Liverpool and during this pre-season match he has proved enough of his contribution by scoring 3 goals in two pre-season matches. With this, we can see that Darwin Nunez is getting more productive and it is hoped that he will also bring this result later when the EPL competition starts. I think Liverpool still have good squad depth for that position and as back-up are Diogo Jota and Luis Diaz who are currently recovering from injury.
I think you are too quick to jump to conclusions because as far as I can remember Nunez also did it last season when he first joined and had pre-season games in fact he scored 3 goals in one match, but after a real season his performance continued to decline and Klopp defended him then said he needed more adaptation. We know Nunez has great potential but besides adaptation he also needs the right partner, this season Liverpool have brought in Dominik Szoboszlai this is Liverpool's attempt to prepare the right partner for him and we have to wait for the official match once the season is running.
I think Liverpool's transfer step was more correct. It was necessary to strengthen the midfield to feed Nunez and they did it, they will. Mohammed Salah will feed him enough anyway. If he is a productive attacker in the midfield, it could be a great season for Nunez. If Klopp saw this potential in him, he could find more opportunities this year.
They bought Nunez as the top scorer in the league he was playing to be one of their best goal scorers and solve the issue in forwards Liverpool had before but the transfer didn't work and I think the best Liverpool can do is to even sell this player.
During the last season, Liverpool performed well and even came very close to winning a champions league ticket for the next season, but in the end, they didn't have the potential to win that ticket and they lost it to Newcastle United. As Liverpool is currently in good form, I think it is possible for them to be an excellent candidate for the Europa League next year.
Liverpool history and potential cannot be understated despite the difficulties they experienced and the relatively unsuccessful season they had last year. They are more than capable of giving Manchester City a challenging title challenge if they have a better roster and renewed tenacity. The inclusion of important players and improved pre season performances point to a stronger Liverpool team for the next campaign. While Manchester City is still a formidable opponent Liverpool is legitimate contender thanks to their talented players and footballing prowess. As they attempt to restore their place among the elite team in the English Premier league expectations for them to win the Europa League and qualify for the Champion League are within their grasp.
Liverpool was disappointed from warning the next champions league ticket in the last few weeks and even Klopp knew his team can't be in this tournament in the last weeks but still I think Liverpool had a good performance in the last season they are currently the first hope for the Europa League.
