Preston manager Alan Irvine believes promotion, play-off and relegation issues in the Championship will all go down to the wire.
Preston climbed into the top half of the table with a 2-1 success over Barnsley - their third win in five matches - and Irvine has been taken aback by his side's rapid progress.
He said: "It's amazing what can happen in this league.
"The result just shows how you can have a disappointing little run and then suddenly go flying up the league.
"It's such a tight league and it's going to be like that all the way through. It has been so tight in so many of the games."
