If you're just going to put our terrible recent recruitment down to luck, there's zero point in a discussion, that's a colossal copout. We haven't been 'unlucky', we've been poor in the transfer market. Which is why Paratici is here in the first place, and is starting to uproot our scouting team. We failed. Even Levy knows this and is taking a step back from the football side of the club as a result.
Nobody thought United's last window was a bust either. It was. You judge clubs on the results of their transfer business, not expectations at the time. You seem to want to excuse the club on its failings on the basis of bad luck, or sportswashers, or hindsight, or a million other excuses. The bottom line is they signed players who failed to be successful here.
Liverpool's recent major signings: Diaz, Konate, Jota, Thiago, Tsimikas, Alisson, VVD, Keita. Not possible to get signings consistently right, huh?
He's not the best U23 CB in the world.
Strange how you have the 'balanced' and 'reasonable' take yet so few people seem to agree with you on it, even people who are generally supportive of the ownership. Maybe you need to re-evaluate your own position and think about whether you're being reasonable, or just an apologist for obvious, clear failings that the club itself has recognised.
