Huntelaar or Llorente (different strikers I know but just based on ability)?
Have you watched Pique over the last year? He's been awful. The only reason why Agger hasn't got world class reputation is because he is injury-prone and hasn't played regularly because of this.
Kroos at the moment because Wilshere is one year behind his "development". However, if Wilshere keeps playing like he is, he should be able to overtake him.
