last piece of the puzzle

Many were saying that Dzeko was the last piece of the puzze to ramp a title-challenge... Personally I think we are two players short (three if Balotelli is leaving soon).
Here is my dream and what would really make me feel we are "complete":
1) Sell RSC and Adebayor and bring in Romelu Lukaku. Young but perfect for the PL and as his current coach is saying "has the body of a 25year old". Seems a real gentleman and not a dramaqueen. Yes he is young but would be backup for the three main strikers so no problem. Can not come untill summer though.
2) Don't let Chelsea get David Luiz. We do need another top-top defender. Toure and Kompany doing well but we don't have a real top defender should one of them get injured. He can also cover left back should Kolarov get injured or we need more "height/strength" there.
Both are young and both are top talents, maybe best in world. Should Balotelli leave too I'd take Aguero. Other than these two/three players I'd say all we should look at are youth talents and world class players like Messi etc. (Which would just be a bonus and not a need.
Anyone else watching the transferrumors closely and cannot fathom why we seemingly are not in for these two players?
