About Mourinho selling a lot of players because he "doesn't like them": LINK
Hazard - Hazard is not leaving. There has been no rumor as to him even leaving and even if there was, there is no way in hell that we would sell one of our two best players after they have been here for only a season.
Mata - There have been a few rumors but it would make no sense for Chelsea to sell Mata either. As with Hazard, why would we sell one of our two best players, who loves the club as well. LINK
Oscar - Same with Hazard, there have been absolutely no rumors that I have seen about Oscar being sold, nor is there any reason to sell a bright young player after his first season.
Luiz - In 2010 (!), Mou wanted Luiz at RM and said this about him, "I like him a lot, but he won't come to Madrid this year. It will be very difficult for him to leave. I'm not thinking about him at all this year. There was some contact, but the price is prohibitive." LINK
and He's looking forward to working with the young players, including 'Hazard, Luiz, Oscar, all these player you mention'
So in the end, it is probably not "best for Mata and Luiz to gtfo" because they have no reason to. So shut up, all of you!
