I don't think Klose is 10x better than Trez. That is just way ridiculous.
I DO think that Klose is more effective than Trez in many ways, but Trez would always win on finishing and as poucher.
I would say if we lose trez, and we can get Saviola and Pizzaro on Free, then that would be a good option. Buying Toni or Klose would be another option, but I'd like to save some of our funds for 1 big midfield transfer.
