What is your reaction when your winning slip is turning into how I know???

This is precisely the reason sports matches are fun to watch. Being the heavy favorite doesn't automatically mean the team or player will certainly win. In the same manner that being the big underdog doesn't mean the team or player is certainly losing. There's a game. It will still be played, and with fair rules. Either teams could win. Upsets do happen. Underdogs win, too.

There are others who are fond of risking with underdogs. The odds are attractive. The chance of winning may be low but it's there. And you can lose 2-3 bets but can win only one to recover everything.

I wouldn't believe my eyes, how this big teams disgracefully lost to the other small teams. A goal that came just ten minutes earlier. How are my supposed to know that this smaller side will bite the big team. Just a goal. Till the match end. And it was the last game in the slip.

It seems you are still a novies in the system ? because if are not you are surpose to know how this betting stuff work, no team is pretty sure or gauranteed it just all depends on how things fall for that day. However have seen a situation were by people lost a very huge amount of money all because of similar things like this, smaller team defeating the bigger one and causing massive lost. If you decide  making your decision in your betting streak through this pattern them you are actually a dreamer because gambling normally don't work that way moreover nothing can be too sure just for you to stake what you can let go and have your peace of mind.

There is such a thing as an upset, and there are many reasons why a weak team can upset a strong one; one is injuries, or the strong team overestimating the weak team.
If you're betting on a strong team, be sure to check whether it has a string of getting upsets; it might happen again at the time that you are betting for them, so you will not be surprised.

You are right @robelneo, what I observed too after facing this kind of incident several times is that the strong team sometimes lose the game at the home of the weak team,  so there's reason to believe or assume that these lower teams draw strength from home, while the big team which might have been exhausted in their journey will likely no play well, sometimes the games end in draw.
