One important thing that i was thinking about is that,since ranieri is not creative about changing tam formation,even buying WC players would not make us League competetive like before,cuz even if we have some extra good players,we can not balance them tacticaly.
for exmpale,right now sissoko and zanetti are not available,we can not cover this loss tacticaly,we can not introduce new formation that cover this disadvantage.
like now we have many great attacking players which most of them can play 2 or 3 positions,like alex,seba,IQ and even amauri.but we are wasting our top guns just becuz we have to play 2 defensive midfielder.
so this way,in a long season,if we get in trouble somewhere in our team,there is no way to recover from that ! the only thing that we can do is wait and pray ! look at big tacticians like wenger or hiddink for example,they change their formation all the time,i saw arsenal in these years playing with 1 to 4 forwards.playin with 2 to 5 midfielders.playing with 1 to 3 or even 4 wingers.so the coach tries to make the most out of what he got !
And also consider the losing form of benched players,the disadvantage of rotating system and etc.
