1.Corluka
2.Ivanovic
3.Campagnaro(highly underrated)
...
were the first that came to my mind.
Ćorluka and/or Marquez could have been bought with a little more effort. Then again, we're talking about Cbs here so i'd take Vedran off the list because he's a RB. I want a CB to play alongside Chiellini , not some versatile guy who can play CB among other positions.
I see the names of Ivanovic, Garay, Santacroce being mentioned. We have a young defender in Chiellini and after the Criscito disaster i'm pretty sure nobody in Juve wanted to take a risk with another inexperienced defender. And we have to admit that guys like Garay or Ivanovic may be talented but they are inexperienced, they'll be a risk and we can't take many risks in CB.
We had to go for someone proven and there weren't many proven CBs available. Marquez is the only name i could think of that is proven, quality defender and that could have been bought this summer.
I'm a huge critic of Legro but match after match he's been proving me wrong. Lippi confirms that Legro played great lately and he called him in the NT.
So, Legro-Chiellini is pretty good actually and our coach probably thought that all we need in CB is a back up player. That's why we bought back up's who won't object if they spend time on the bench.
But if buying Mellberg and Knezevic can be excused and justified, there is no excuse for not strenghtening the flanks with starters. This is the main problem in our defense, it's the LB and the RB, not the CB position (even though i'd like Marquez).
Ćorluka, Marquez and Grosso......all cost under 10m euro and with some 20-25m euro we would have really strenghtened our defense.
