Let's have a look at the teams who have recently won the championship.
Newcastle- brought in a top striker for this level in Gayle for about £12 million or so.
Burnley- Brought in a top striker for this level in Gray for about £12million
Bournemouth- brought in a top striker for this level in Wilson for £3million
Leicester- Brought in the likes of Vardy, Mahrez and Wood.
Cardiff- Brought in the likes of Mutch, Bellamy, Maynard etc. for a lot more than we've spent
Reading- brought in a proven, quick, powerful forward in Roberts
QPR- massive wage bill with the likes of Taarabt. Having chucked money at it for about 2-3 years.
Teams with budgets like ours don't win this league. Now and again, one sneaks into the playoffs and might even win them (like when Burnley beat us in 09) but even then, people kid themselves that Huddersfield are a relevant comparison. They're not. They spend about £2 million on a centre half the season they went up. They also had the likes of Nahki Wells for about £1.5 million and made great use of the German market.
