The article has been written presumably to out Leterme as a weak willed excuse maker for clubs who break FFP, and paints the Portuguese judge as the legitimate, fair arbiter of who's following the rules. Whoever leaked the information, we could assume, wants to put pressure on Leterme to be hardline for once and actually do something.
The problem with that assumption is that Leterme is already an enemy of Manchester City, who according to the club is corrupt and decides cases based on who he wants to pass/fail. If Cunha is actually what the article describes him as, then he will rule with City if we are in the right, even against Leterme's wishes. Releasing this article isn't going to add pressure to Leterme because he's already hell bent on failing City.
A lot of people in this thread are saying this article is basically confirming the Portuguese judge is going to fuck us, but if you look at it objectively, it's actually saying that José Narciso da Cunha Rodrigues is a proper judge (12 years on the ECJ) who doesn't follow Leterme's bullshit and has a track record of speaking up when something doesn't add up.
And if he's prepared to overrule Leterme on saying PSG are innocent, he might well overrule Leterme saying City are guilty.
