Liverpool have a stable squad and I believe they will do well comes next season.Their performance under this coach is really good that was why they flogged Arsenal,and they have now defeated Man United too.
Arne slot seems to be a good coach that will elevate Liverpool again.Although they've not gotten a signings yet,but they are making use of the players they have to make things happen,it might happen that at the end of the transfer window,they won't sign in a my new player if they believe they can go far with the current squad they have.
Defeating Manchester united is a thumbs up for Liverpool but not what should be relied on or be used to judge how good the team could do when the season actually kicks off as these are just pre-season friendlies with some of the players are still new to the squad and still trying to blend and understand the style of play.
Despite winning against arsenal and Manchester united it would be an added advantage to the Liverpool tram that they get to sign a few players to the club who could cover for injury periods because for a team that's playing in the champions league and EPL making for available options is very important to maintain relevance within the season.
