Consistency ? Hammy.. your main pivotal players are either waiting to leave (Valdes ) getting injured way way too much (Puyol ) too old to give the same 100 % all the time (Xavi ) .. you lost Villa , you lost Abidal , you lost Thiago , you loaned your most promising youngster to Everton
You have a player who didn't play enough last year like Song and someone who didn't shine as you hoped he would in Cesc & Alexis, you have a new player who fell to anemia before he started an official match and will take time to adapt from Brazil to Europe (from what i seen in the few minutes he played) a midfielder who get exposed when he plays a CB because you don't have any more CB (Mascherano) , a full back who step in as a CB because you don't have anymore CB (Adriano ) so who you have left ?
your first , second , third , 4th , 5th CB of choice you missed out on and we are 25 days of the end of the transfer season which means he (if he ever comes ) already missed 2 weeks off the pre-season , moreover a new coach who you will still test to see what he will do
I think you should be more worried of a repeat of last year CL issues but so far what we done in the summer and what i saw your management did so far... i wouldn't want you to be worried about us at all
