I don't like this stuff, but I don't care about it for the following reasons:
1) No evidence he spat directly at the player, Marca manipulation as far as I'm concerned until they show a good angle replay to prove it
2) Costa has been on fire with headbutts and crazy tackles (ankle breaker on Ozil) so he can go rot in a hole
3) Despite the shenanigans the players themselves let the incidents slide, because they know there is no point dwelling on it. They are grown men, they know what they are doing on the pitch and if they shook hands I'm sure they would be just as willing to say sorry to each other for what they did.
Firstly, he didn't call him Mono Burgos, the reporter who asked him about the incident on the bench did and I doubt Burgos even cares about the whole thing right now in this moment. Things happen in football, it's a man's game, you'll always get some banter and mind games. And that particular thing, again, blown completely out of proportion by Marca.
That paper for years has been guilty of hiring and firing managers and Mourinho is the first one to fight back against it, that is why they print all these sensationalist articles and increase the amount of negative information as the team is going through poor form just so they can use it to get more sales and readers. But you don't care about it do you? You don't care about what Marca puts out as long as it makes RM look bad, hm? Where is the proof Ramos spat directly at Costa? Why did they mention the incident, but not the fact that the players let it slide at the end of the game? Why is there so much rumors about poor and untrue situation backstage with Florentino who is supposedly pissed off with Mourinho? Because Marca and AS are sensationalist assholes looking for attention, just so they can make money off of the situation and make Madrid own-fans dislike the team more instead of supporting them through tough time. And they will be particularly successful, because they won't have a manager point out their reporters' stupidity during every conference. I ask you again, have you read how many times Mourinho asked them not to ask pointless questions about his future and they STILL asked them instead of being interested in the game that should go down that evening? How many times did they ask about poor morale and him losing the control instead of the actual football matters, like the approach to the game? Ever since he went as far as to embarrass these reporters by responding something like "this question does not deserve an answer" and indirectly tell them they are liars when they said he has not prepared for the next season, Marca started fierce offense against him. The information they put out has such low credibility that it is not worth leaning on in any case.
