I agree with that Vlatko. Although it is hard for me to discredit DD for his tactics. He has a job to with Juventus and I am sure he is concerned with keeping his. Bojinov could do it next year, but there is a lot more certainty in a guy like Pizarro. I have no problems letting someone ride the bench if Bojinov gets the job done. The only problem is that the fans of the one riding the bench will see it as unfair. I say, bring in Pizarro. If Bojinov isn't cutting it sit him for a later date. If he is, then let Pizarro ride the pine. Either way, with Trez here and healthy, playing time will be scarce. I prefer Bojinov, but wouldn't hesitate to bring in a good striker on free transfer.
BTW, if we had to replace Trez we would need to buy a player like Toni or Klose. Trez is one of the top strikers in the world. Hard to replace.
