I tried sorare a few months ago but i did not invest any money into it. Then i "played" it for a few match days but i  found that the game was pretty boring, as there really is not much to do. You just register your Team for the matchday and hope that your players are performing well or even get to play at all in the real world because that is where sorare gets it's player ratings from. So if you only have a free team without expensive players you don't have a chance to be successful. That is why i stopped "playing" sorare.
