Not sure what Liverpool's plan is - both Frimpong and Kerkez are extremely offensive players. If both start, the team composition won't be as balanced as it was this season.
TAA was also not great at defending to be honest. This is why I think Frimpong's arrival won't change things much there in terms of defense. Arne Slot must be prioritizing attacking much more considering his choices.
There is Wirtz as well. He is like a wonderkid actually but Liverpool still spent €125m for him which is an insane sum. He will have a lot of pressure on his shoulders. In case Nunez leaves they would make use of a new forward too.
