I'm not worried, Levy has had the odd bad 12-18 months in his tenure but he quickly catches it and turns it around to an even better level. The big risk was the Poch implosion happening when we were at our first season in Wembley, it could have had a real impact on our finances and decisions made, we have got past that.
Our income has improved and the club will spend more on players and wages (already seen last summer), will we outspend Pool or United? = no, but we are a better run club, so if we are close enough then we can compete.
I also think the part people miss when talking about how Poch was or wasn't backed is the fact that Levy was probably focusing way more on the stadium that anything else for 2-3 years. With his attention back to on the pitch matters and if the rumours of DoF (Lille guy) are true, then again, perhaps lesson learned and we move on.
I was here when Hoddle, Jol, Redknapp, AVB, and Poch left, and the narrative was the same, we are never going to do better, this was our opportunity, the sky is falling, our best players will leave, we will go back to mid table mediocrity, etc. etc.
Spurs is legitimately a top 6 club now, with what will likely be top 3 or 4 income, and yes we will have brick years, but our profile, location, income and the way the club is run will keep us there or thereabouts .. keep the faith
