Liverpool wants to retain their Premier League title when the new Premier League season starts, and for them to do that, they need to build a squad that can consistently win matches and other clubs in the Premier League will find difficult to beat before they can achieve their goal of retaining their Premier League title next season. The next Premier League season is yet to start, so we don't know if Liverpool's lineup next season will be scary. Let's wait until the new Premier League starts so that we can know if Liverpool's lineup will be scary or not.
Yes, Liverpool are also working very well in the off season. They have literally just announced the signing of a defender from Bournemouth, Milos Kerkez. I see that they signed him on a five year contract. Actually, that is a very long deal, but considering that Kerkez is only 21 years old, I think it makes sense. The most important thing is for him to settle well in the team. Slot is making the right moves. Liverpool need to strengthen their defense, especially after Alexander Arnold left the team. I also see that most likely Liverpool want to sell Nunez because Napoli are showing very strong interest in him right now.
