There's lots of ways to look at it, but realistically, I'd rather be 4 behind a team not long out of League One, selling their better players with a goal difference that would just about be retrievable, than be 5 behind a stronger side with a proven very good striker almost back and with a goal difference advantage which pretty much won't be caught.
The bookies suggest us, Burton as almost gone and then 1 of Barnsley, Bham and still Bolton so while its going to be tough regardless, if we can keep to within 3 and 4 points of those aforementioned teams then I personally think that's our best chance of staying up and even then it will still be a long shot.
