City was genuinely interested, but with Mancini on the outs, who knows how many clubs are currently after the player, or what his price will be? The environment at Fiorentina has obviously changed since the end of last season. Regardless, this talk about him being worth only 15M is nonsense.
We got Vuci for 15 because there were issues, he was out of favour at Roma, and because he was established as a widely inconsistent player. He's also older, so there is no premium for potential; we knew exactly what to expect from the player, and frankly, he's come as advertised. If Mirko could play at the level we know he's capable of consistently, he would have been a more expensive player.
Also, Llorente is, what, 6'5", so there is a bigger player coming in attack.
