I don't know why a strong team like German and Morocco didn't play seriously when meet in a friendly match. this will be noted and experienced in the future, So if you are bet in a friendly match, be careful to bet, don't look at how strong that team and squad, just look and be brave to bet in a draw. This is just my opinion, not always all friendly matches result for draw, but with my 3 last bets, I have a thing to bet 70% in the draw 
,
how about you?
To be honest, I have never won multibet or single bet on friendly match so far, anything, including big clubs in Europa. Indeed, it is difficult to predict because the match is not as important as chasing a trophy, so both clubs or countries are not playing too seriously. The results are unexpected, even we often see draws results like your bet. Right now it's better for me, not bet on matches which I don't understand, or matches that aren't too certain like friendly matches because the results are often disappointing., how about you?
I can totally relate to your experience with betting on friendly matches. Personally, I've never had any luck with bets on friendly matches either, so I now avoid them completely. The thing about friendly matches is that they lack the motivation that you typically see in competitive matches where teams are fighting for a trophy or a title. Since these matches are more like practice sessions, the teams involved don't always give their 100%.
One example that comes to mind is a friendly match I once bet on between two top-tier European clubs. On paper, one team seemed to have a clear advantage, but the match ended in a surprising draw. Of course, everyone's experiences may vary, and some people may have had success with friendly match betting. But for me personally, I now focus my betting efforts on matches that have higher stakes and where the teams are more motivated to win.
