She didn't hurt Iker. Saying she hurt Iker pretty much implies she did this despite him or without him knowing, which is highly unlikely. She hurt Mourinho and his followers, and somewhat hurt the club's reputation. But only to some extent, only within the context of Mou making a mockery of the club in the first place. Iker's place in the team and in the club is fine. He mostly won't even be playing for the rest of the season, so it's not as if she could cause Mou to bench him again or anything like that. Surely, there'll be RM supporters who will dislike Iker for being related to the person who blabbed out in the media, but that's only a short-term thing. Once Mou is out and the club is back on its feet, however, Iker and Sara and the rest of that party will be seen as the good guys.
