We used to talk about the great leap in quality from the Championship to the Premier League. Now it is only the feckless or the flawed who need to worry.
If you want to come up from the second tier and threaten the upper echelons of the top division then, sure, you will need to spend some money well. Or have a manager like Sheffield United's Chris Wilder.
But if I were a supporter of Leeds or West Brom — currently occupying the top two places in the Championship — would I look at the clutch of clubs in and around the bottom six places of the Premier League and worry for what could happen next season?
