For me, not signing a CB to address that defence is a sackable offence.
Maybe, but is hiring new players done by Klopp? Or there is a director or something than does the thing? Maybe Klopp asked for that but the director messed up with Van Dijk and then he couldn't get another either for not having funds, considering the asking prices were too much, in which case Klopp wouldn't be the one sacked. IIRC Klopp did talk about CB not being that much of a necessity, but even if he appears a bit nuts that doesn't mean he can't know to be diplomatic and tell a lie to the press to avoid making the club appear as incompetent or ignoring the manager, as we all know how it'd be if he said something like "I've asked for a CB, we need a CB but these guys can't do their job properly".
Personally, after following somewhat news and stuff about signings in Real Madrid basket section, I refuse to think I know who signs. We had Ettore Messina and we had first that he made the signings, but later he didn't do any signings, specially since it was clear he didn't want Begic but got forced to move a player off the team that then almost no signing was his; then he was replaced by Pablo Laso after two disappointing seasons (he did resign after a shameful performance of the players against Montepaschi, looking very much like not wanting to win, the one time I could believe that recurrent idea of players trying to force a manager out). Some signings happened of players and even in that first season the signings were made with him, by him or at his back. My theory is the cleaning lady picks a series of basketball magazines and throws a few darts, then they pick whatever player was hit.

As for the knobheads, they're everywhere. I'm Spanish so I only have a few English followed, from FM things, so I see very little of Liverpool or non Spanish news, my TL is 90% Real Madrid fans, so while those I follow directly are mostly decent, I still see a lot of RTs of such knobheads. One day I'll roll my eyes so hard they'll fall off and reach Vladivostok before stopping. Probably the worst knobheads: they make a storm against sports press when it talks **** about some of our players (foreign players, because our press is not xenophobic, no sir), but give them a few months/days, wait for that guy's first not great match and then they'll be repeating everything the press said, even if the facts on the pitch are incompatible with them.
The first sin of everyone: They never consider there is a rival who also plays and can do things right, too. It's like they thought "my team is the only playing and the opposition is an AI team with a set difficulty, that considering my team is the best, has to be, said difficulty can't be higher than easy". Not to mention that paradox that if you read them: the best players are those not at Real Madrid, the Real Madrid players are ******, starting by Ronaldo and Bale, and they're Segunda B level, but it's unforgivable if they don't win against Bayern Munich. It's sooooo annoying at times to see the football tweets. Of course, if I'm watching the match, whatever similarity between what I read and what's happening is pure coincidence.
