I'm not even sure what you're trying to argue anymore. Threats or no threats, no keeper of MAtS' age and talent will be happy playing as little as he has. When he signed, I very much doubt that he was told he'd play that little during his first two seasons. If anything, he should be commended for not forcing a transfer earlier.
Now Lucho and Unzue has clearly agreed that the German is ready to take over for good, and Bravo is understandably enough not one bit happy with it, thus accepting Pep's advances.
And that's the funny thing here, and what I bet rubs you the entirely wrong way; Pep wanted MAtS first, but Barça and himself rejected. Why is that? Simple really; because he's good enough to equal what Bravo did here and has a higher ceiling, cementing his place at Barça for the next decade or so. Why did Pep want MAtS first? Because of the exact same reasons. Bravo was always his second choice, and that makes you mad, as he's practically been deemed second best by not just Barça, but also Pep.
I'm sure you will slither back here and gloat whenever MAtS makes a mistake. Because he's bound to do so. Luckily he has so many positives going on for him that it outweighs these mistakes, which he in turn will iron out as he gets older, wiser and even more established here.
