TV money has done a tremendous amount to level the playing field. It's ironic that as football becomes more of a business off the pitch, it becomes less of a business on the pitch with extremely strong competition and no-one really dominating the marketplace of success. I don't think we'll ever see the likes of Man United's domination again in the PL era.
RDBD has a good point though...the 'little' clubs (now all in the world top 30!) would do well to look at the oftentimes horrendous investment strategies of the 'big' clubs and realise that it is more important to invest wisely than it is to invest broadly. Some of this season's less successful clubs have massive net spends...Palace, Newcastle, West Brom. And relatively speaking, you should include Liverpool, City and United in that list. None of those teams have improved whatsoever on last season despite spending that much. The irony of not having the correct strategy and strategists in place is that they've actually not improved because they've spent that much.
It's an extremely opportune time to be a Spurs supporter. No one does frugal, pragmatic spending quite like us (with the exception of Balegate). And, as TV revenue increases, I have faith in Levy and Poch that the money will be wisely invested. We might not appear to be the most ambitious in the league during transfer windows, but as the Manchester giants have demonstrated...there is a fine line between ambition and recklessness.
