In the “Competitions” section (fifth button on the menu) you will see when you will play your upcoming matches. You have to connect at the time you are scheduled to play (or just a few minutes before) and access the match in order to be able to oversee how your team is playing and make the changes you deem timely.
A bright blue and red option will be activated every time your game starts and to access this option you just will have to click on it.
If you cannot connect at the time of the game, it will take place anyway.
