I've already mentioned how Conte is at fault for both goals conceded against Chelsea. Tactically, leaving Tanganga on for 10m after half-time lost us the game.
However, the other thing that has let us down is squad building.
Under ENIC, it will be a disadvantage forever, and ever, but it is worth pointing out just what a difference it is to have Levy and Lewis as the deadweights in charge, against ambitious owners.
We are 23 days into the window. 23.
We've clearly wanted a right back for months. We will leave it to the final week, maybe the final day. Who knows what a new RB would have done here - how different this could have been.
We wanted a forward to back up Harry Kane. GHod knows if we'll get one before the window closes.
We wanted a center-back. Likewise, GHod knows if we'll get one.
In a window where Antonio Conte, the best manager we've appointed since Poch, has been begging for reinforcements - we have given him absolutely none.
And as a case study, it is interesting to see what a difference early transfers can make.
Aston Villa appointed Steven Gerrard a few weeks after Conte. They have moved fast and hard to back him, bringing in Coutinho - who then made an instant impact at United. Digne - who made an instant impact against Everton. They have helped Aston Villa pick up points they may not have done if they had not arrived.
Who knows how different this game could have been, if we had been proactive - for once in the twenty years of Levy and Lewis' miserable, parsimonious, grinding, depressing rule at Spurs.
Aston Villa, a club recently in the championship, moved faster than us to back a manager whose biggest achievement was winning the title with Rangers.
We left Antonio Conte, one of the game's best managers, high and dry.
What we we do now may salvage the rest of the season. But ultimately, our utter inaction for three weeks shows once again how Daniel Levy has learned absolutely nothing, and never will.
Penny-wise, pound foolish. Should engrave that on his damn tombstone.
