They become angels of death. They managed to kill Madrid and Shaktar. I don't think it's luck, but thanks to hard work. But it could also be because Madrid and Shaktar underestimate him too much.
I don't think Real Madrid and Shakhtar got loses because they underestimate Sheriff. Sheriff won because they played well and be confident without any pressure. Sometimes, once you play nothing to lose, you can optimize the chance to win. While those teams that play with too high expectation, can be defeated since losing focus and control during the match. That's probably happening to Real Madrid and Shakhtar.
Yes, whether it was due to luck or underestimation what is certain is that the Sheriff can do it with good hard work during the game. But if the Sheriffs can still win against Inter, then maybe I'd say it's a miracle created by their own hard work. I'm just curious what the final standings of this group will be, because previously we all agreed that the Sheriff would only be an opportunity for the other 3 teams to gain points, but what happened was the opposite and of course we were all surprised by the result.
So far I personally consider the sheriff's two wins to be a stroke of luck, especially since Madrid are clearly very weak in their defense this season, so I really agree to see the results of the sheriff match against Inter as an answer to what we've been debating all this time.
