Scouts are useful, but you are better off buying young 5 stars early in the season and then using the tokens you would have spent on a scout on green packs to train them up over the course of the season. Like I said, scouts are there for the same reason candy crush has boosters, they might help you win, but they aren't a guarantee, you just need to make the right moves with the board you have. Spurs just beat Man City because they have strong young players that are multipositional and offer a lot of problems. They also have a world class GK and a few academy graduates in their squad. Don't be Man City, bro. You can only buy trebles by manipulating your cup and league draws, if you aren't prepared to do this, then you are better off taking the long road to success.
