What Liverpool needs to is get new contracts for current players and not think about getting new players. Mo Salah might be getting old but he has 2-3 more years in him and can give a lot to Liverpool. The only thing is if Mo Salah isnt greedy for money and takes the saudi deal. Trent is replaceable but is still really a good player for Liverpool
Yes, retaining every player that Liverpool currently has is very important. Because so far Liverpool's squad is the best composition compared to other teams' squads. And maybe for now Liverpool doesn't need additional players. because both in the main players and also in the second tier we have seen a good balance formed in this team. All of this is thanks to Klopp who has put this team in a mature stage. So Arne Slot just needs to continue and improve it. And trying to extend every player whose contract is almost up is important, especially if they are the core players on this team.
But maybe this is only good for this season and the next few seasons. Meanwhile, in the longer term, perhaps this team can start hunting for talented young players in the next season. but not this season. Because this team is already balanced and don't let the presence of new players destroy the current balance.
