Is it a problem of strikers combination??

I dont think its the problem of a striker combination for shevchenko because he and drogba can perform decently well togetther but i think shevchenko just needs time to adjust in to the playing style of chelsea and in a sense has to come to terms wit hte fact that he needs to get back and defend when chelsea dont have possession. Something quite difffernt from when he was ay AC milan where his only purpose was to be the target man and score goals.

i think sheva didn't peform well not because he not combine with his partner which is drogba but because the formation not good for his play style

At AC Milan he has players like Pirlo to feed him all the good balls. At Chelsea Ballack plays this role but Ballack isn't doing his job well!! How many times Ballack gives good balls to the strikers? How many assist he has this season? If replace Ballack with players like Pirlo, Ronaldino, Diego and all those playmaker type then Shevchenko will receive more support.
