I guess. But knowing our luck with injuries, we could very well end up playing 3 or more primavera players each game. Personally, I'm not too comfortable with that.
Then again, I'm not too comfortable in playing Grosso either :D
You'd need a squad of about the same size we currently have though, so getting rid of 8 or 10 players means bringing in 8 or 10 new ones. And if you're just replacing mediocre with mediocre, then I don't see the point.
