Our Biggest Problem

After deJong and Tevez returned we see a different performance. As a lot of speculation went on as to tactics.. players motivation.. not good enough etc etc.. what is the feeling now.. what are our main problems?
Im still thinking that it is a mix of individuals getting used to the prem and the team getting used to each other on the whole.
The only other thing is that deJong makes such a difference to the way we can play.. he is just almost 100% reliable at protecting the defence and patrolling the loose players hanging around at the edge of the area when teams are attacking us. He is truly something and the only concern is that without him we have no-one else who can do his job or even anything close to it.
Other problems are seasoned Prem players not getting a level of performance out. SWP recently to name one, Bridge.. are just not reliable enough.
The new players i can excuse so far as they have to learn.
