This is a good decision, just look if Liverpool is without Moh Salah in the match. Liverpool have more difficulties when facing big teams. This match can be an option for Arne Slot to have time to get a replacement for Moh Salah properly. So Liverpool did not take long to make adjustments when Moh Salah left. After the contract extension, Arne Slot had to immediately look for a character player like Moh Salah to prepare for the project when Moh Salah left. Arne Slot must make good use of the transfer market this season. There are some names that I think are good such as Khvicha Kvaratskhelia from Napoli and Jarrod Bowen from West Ham.
If they can get Kvara, the Georgian player can contribute greatly to them. Liverpool's midfield is currently the best in the world. We saw what they did against Real Madrid. They also crushed Manchester City. Although they don't have the best players in the world right now, they are the team with the best harmony. They have a very high chance of becoming champions in the Premier League this year. They also gained a great advantage by winning all their matches in the Champions League.
Khvicha doesn't have much experience playing with big teams and the only one is Napoli, on the other hand he also hasn't really shown himself as sharp striker with Napoli even though his performance in Serie-A has been quite good, I not sure Khvicha will be able to replace Salah because the competition in the Premier League is very different from Serie-A.
And I think you should be able to understand that Real Madrid and Manchester City are in bad shape, if they both have good condition I can't imagine whether Liverpool can destroy the two strong team, but I admit this season Liverpool is the only team that can perform consistently overall.
