Friendly matches are not a worth to see games, they were played without fierce, and we see so many tries of players and tactics.
Some games are played with subs players and the one with starters are played without the real energy of a game, no one its gonna risk a injury. Thankfully its gonna end soon this part of the season called pre-season.
Wagering on pre-season games is definitely not what we expect to happen, in positions to forecast accurate predictions. In preseason games, elite clubs mostly lose to average clubs, that's totally understandable, and it doesn't even surprised me, ready to face the outcomes of these games. In pre-season games, it's consider not important and players do participate for fun. On the other hand of the coach, he utilized his players, giving gametime opportunities for every players in his squad, also a means of selecting the first XI when the season begins.
