Surely a new centre half is imperative. There is a world in which we're lucky where Matip/Fabinho/Rhys/Phillips could possibly be enough for the next 5 months, but it isn't happening is it? Not with Matip.
Fabinho is world class and has been incredible at centre back, this spell of his LFC career won't be forgotten, but it'd be nice for some games to even have the option of putting him back in midfield, and a new centre back could provide that 'luxury' - or at times partner him or one of the younger lads at the back. If we do get a new lad in and he hits the ground running alongside Matip, it'd be delightful.
After the window opens we'll still have a big 22 league games, and the two leg tie with Leipzig, with hopefully more football in that regard, that's a lot of matches. I'd really like it to be a situation similar to Van Dijk where he was signed and ready to go straight away, but suspect we'll tie someone up in January
