Ok.. so unless you have a big name midfielder that you've had from the start... and you're keeping him for the season you maybe thinking what im thinking....."everybody is letting in goals left and right, and the whole thing is very unpredictalbe"
who then are the budget players with good rotation between each other...
I currently have:
Jones (keeps getting injured cant get in form ) would do

kompany but MC are not a CS-machine either.. so mabye CLICHY
knowing that he's a rotation risk but the idea is to have 5 any of which you'd be ok with playing
Simpson is it time to go? i think ill keep him for time being
shawcorss tired of him maybe

bosingwa as he plays and despite lack of scoring Che to keep clean sheets ... i guess
BAE 
Caulker bc not so good fixtures coming
McAuley 
brown...
my man U defense will be Lindegaard and then Mignolet..... getting rid of Vorm/ruddy
Im also thinking Kelly maybe a shout..
Who are your top 5/6 budget defenders... ???
Mine look to be:
Simpson, Bosingwa, Caulker, Brown, Clichy That does sound like a motley crew but the idea is that it's really hard to predict who gets consistent CSs these days.....
