With the transfer window closing, the madness of the money spent is unfathomable and it is not just those super clubs.
Boards of directors dissect data, analyse algorithms and try to be as scientific and mathematical as possible. The results however appear stubbornly random for different clubs, some are ultra positive, others utterly negative.
Newcastle just about broke even with their sales and acquisitions this summer. They have lowered the average age, but also slashed the experience available for Matthias Jaissle to dangerous levels.
Meanwhile, Spurs splurged by spending a third of a billion pounds (and counting) on four players, even if they did scrape a chunk of that back on sales. The upshot was a 2-0 defeat at home to the travelling Toon Army.
The sample size is too small to judge though and with Roberto De Zerbi at the helm they might still come good after losing both opening games without scoring.
Spurs fans do however have the right to wonder, "why have we spent all this money and still haven't landed the striker we so obviously need?"
Reliable quality in the final third is what costs most just now, because it is such a scarce commodity.
