For the previous few seasons Liverpool could still do that but for now I want to relax my expectations for Liverpool because although they at the beginning of the domestic competition they played very well but in the end there are still doubts for Arne slot in this regard.
Liverpool can play well in the champions league as they have a history of winning. It is the same history that is helping real madrid to always be the team winning every time too. Liverpool already has 6 champions league therefore they can win more with or without a stronger team. Let say Real Madrid and Liverpool meets at the champions league final, Real Madrid might still win them as they have a better squad but it isn't going to be easy for Real Madrid as how it would had been when they hey meet a smaller team as Arsenal. Arsenal aren't a champions league team as they do not have any experience or heritage in the champions league.
Last time Liverpool won in the 2018/19 season and lost the final afterwards in Klopp's heyday at Liverpool and Klopp also needed a few seasons of trying before finding a good formula and this season I think I'm still quite rational if in the end there are still a few doubts about Slot in all the competitions he has with Liverpool.
