Nope. We spent a shitload of cash to build a good championship squad. Nowhere near close to being good enough to "guarantee" promotion. e.g. last time we were down our squad was good enough to nigh on guarantee promotion, and few if any of our current squad would get in that team. Our squads (yours and ours) are comparable, but we had to build ours in 1 summer.
We spent about £0.5-1m per first eleven player on average, you spent about £5m on your equivalent. They're not even vaguely comparable.
Players like Matt Ritchie and Jonjo Shelvey are FAR too good for the Championship, and came - when no doubt they had Prem offers on the table - because you can offer them silly money.
