For me, any transfer business we do in January still depends on the next couple of weeks beforehand. If we go out of Europe and are quite adrift of top 4 then I’d say leave any major business till the summer.
Klopp was criticised massively last season from liveprool fans for not being ruthless enough so not sure why you think the opposite? It took a really poor season and them missing out on top 4 for them to act. Even they they only reshaped the whole midfield because Henderson and Fabinho left.
