Mmmm.... I mentioned here in the beginning of the season that Deco would be a great signing BUT that he would need regular rest. Maybe you think his great start of the season was just a fluke. It's possible. I doubt it though.
Quaresma, on the other hand, is a match winner in a team playing flowing football. The Chelsea of the beginning of the season would fit that, but the current one wouldn't. Neither does Inter.
As a Portuguese, I'd love to see him do well because I know he has the ability to do much better than what he's been doing at Inter. On the other hand, I want Scolari to do as badly as possible.
Edit - That said, Scolari always benched Quaresma for the NT, even when he was by far the best player in the Portuguese league. I don't see why he would go for him now. If this was a board decision and Scolari isn't in on it, then he'll probably just let Quaresma rot in the bench or play him in the last 5 minutes of games..
