Like Southampton when they lost their manager and sold all their talent?
Our managers gone, but the squad improves, it will all depend for me on who the next manager is imo.
If its someone who knows top level football (Hiddink, Big Sam, Laudrup etc) i'd be thinking we can get a comfortable 10th-14th place with no worry of relegation, whereas if its an unknown talent at this level (Lennon, Coterill, Dyche etc) i'd see us in a relegation scrap, floating in and out of the relegation zone.
The teams that came up last season didn't exactly walk the Championship either, so they will need to make a few good acquisitions this summer.
Just as an FYI i included Dyche in the unknown list as you can't really count last season for him, their squad was championship level and their owners were unwilling to roll the dice to buy players to keep them in the division, yet they still battled well. Even top managers would have struggled to keep them in the league.
