So define success. is it winning trophies or reaching finals or coming close eg top four? Everyone outside of Man City infers that their money lets them win things. If that’s true then everyone else is a runner-up unless they can spend the same. For Spurs that ain’t gonna happen. Even if ENIC and Levy are gone the spending power will only change if the club becomes state-owned where the money is no object. As that’s unlikely what would you have new owners do? The reality is Spurs ARE successful achieving the mid to top end of the table and overachieved in the Poch era by consistently reaching top four.Next manager when Conte quits?
Since Poch, Mourinho and Conte (probably) all failed miserably I don't really care who it is while Levy/Enic are around because they'll fail too.
