Levy, Mourinho, Mendes and Hitchen/scouting team.
We've spent money, but we've not paid ridiculous amounts for anyone. Not sure what the estimated total spend is now, but to get potentially 4 upgrades in the starting 11 (Doherty, Reguilon, Hojbjerg, Bale) + a backup striker and a backup keeper for that amount is great work. A fairly similar amount to what we (and others) have paid for a single player before. To have several of those signings fit in so quickly (so far at least) as well is rather astonishing.
