No, use Crisetig in your youth squad. He's 17 and turns out to be quality. I was thinking of getting a replacement for him too in my Inter save, but ther's no need. Otherwise, if your playing Cambiasso as a Cent Mid box to box, I'd get Rodwell. If just a Def Mid, I'd go for M'Vila. But what I'm doing is using Miagara (sp) or Munitari until Crisetig is old enough. Cambiasso is only 30 as well so he should be fine for 2-3 years, plenty of time for either a good regen to join your youth squad, or just time to find/spend on a good prospect.
