Im pretty sure Barca/Madrid had an interest in Martinez too, and it looks like he is going to Bayern, least last i heard it looked likely, maybe its died down now seeing as hes still at Athletic. Besides, Barca havent played with a target man in God knows how long, and Madrid went for Higuain/Benzema.
Either one of Llorente or Dzeko would be a good move, and as someone said earlier, it will be down to the wages which will decide on who we end up with
