I don't think the situation at Inter is such that the coach is at risk of being fired. At the moment there is only 1 bad result, which could be a simple fluctuation. I think the quotes (20%) reflect precisely the fact that he is unlikely to be fired even if the next result is unsuccessful. But there is definitely intrigue - simply because Inter plays Juventus in the next round. A loss of points is very likely here.
Agree with you the situation is simpler than people think and I think coach is still in the safe zone. As we know, we cannot describe Inter Milan performance only in the last 2 matches if they lose in 1 match it is still normal even though it will increase their burden. Just like you we are looking forward to next week big match between Juventus and Inter Milan or we can call it a challenge for them, if Inter Milan can collect at least 1 point then they are safe.
