Birmingham City (relegated after 2010-2011), Blackpool (relegated after 2010-2011), Wigan Athletic (relegated after 2012-2013), and Fulham (relegated after 2013-2014) are the bottom four clubs in League Championship. Can anybody find a season where the bottom four clubs in League Championship (you can use a second division season when the league had a different name) had all been in the Premier League within four seasons of that season?
No idea, you'd expect them to be at the top end of the table with their recent parachute payments but maybe Financial Fair Play has clubs tightening their belts and them being recently relegated from the Premiership they probably have the biggest debts/deficits and are being hit the hardest? The recently relegated Championship clubs are struggling in League One as well, Barnsley are pushing up the table after a poor start but both Doncaster (17th) and Yeovil (bottom) are having a hard time of it.
