Yes, Liverpool have great players and they have won the Premier League this season and were in good form in the UEFA Champions League. Although they don't need much in the transfer market, if they can sign some good stars like Mohamed Salah, the team will be more complete. Moreover, if they can play in the same way as they have done this season, they will be at the top of the Premier League next season. However, how well they play in the Champions League and how much they dominate will depend on their performance. However, it is true that Liverpool will definitely compete strongly next season where they will try their best to succeed.
To some extent you're right but we have to note that last season performance is never a determinant of the coming season and some clubs will perform below the previous season performance while some will perform more better than how they did the last season. Almost every club is trying to strengthen their squad against next season and some of them even changed their coach for performing poorly last season. This shows we are going to witness an intense competition the coming season and Liverpool will feel the heat to defend their championship. Amorin is very lucky with the squad he met and at the same, they adapt to his pattern quickly. Hopefully, he may uphold that consistency in the coming season.
