There are matches where it is let's say 86 minute but you can see that the match is over because home button changes from bouncing ball to standard icon. The match is still going, you can see 1-2 attacks but you can predict that there will be no more goals because of that change. And vice versa, if it not changing, you can hope for a goal during the last minutes. I don't know if it is true or not but this is my observation.
