At City, he'd have to compete with Nastasic correct, but Nastasic has been injured a lot this season and he's certainly an improvement on Lescott or Demichellis. City play with a high line and build from the back so Luiz could be ideal for them, especially next to a very solid leader in Kompany (who also gets injured quite a bit). United... I don't rate any of their CBs apart from Vidic and Jones. Vidic is nearing the end of his career, so is Rio, Jonny Evans and Smalling aren't as good as Luiz either. Bayern have a solid core of defenders there but due to the way they play under Pep especially I think they'd potentially be interested too. I think Luiz is possibly better than all of their CBs when on form too but that's just my personal opinion. Now I'm not saying that all these clubs would definitely be queuing up but I'm sure that if Luiz was to be made available on the market they'd look into the possibility of it. PS: sorry for going off topic. Would be nice if this discussion was moved to the Luiz thread by any of the mods.
