Martinez is being sillly, he doesn't want to leave and is being talked about up near the £100m region and we're not spending that sort of money.
Loftus-Cheek is a strange one, he looked a really good player about 6-7 years ago but he has had so many injuries that I just can't see him ever being the player he could've been. Aside from that, despite a year or 2 without anything major I still wouldn't trust him to stay fit. On that basis I just don't see the point, even if it was a pretty low fee.
