Tips for beginners?

[Crimxson]

Heya guys, Im new on this game and I would love to get some tips and guides.. I know there are a lot of those in the forum but I cant simply find a useful and easy way to start the game.. sooo here we go
As a beginner, what is the best way to buy players? A balance between quality and spending, idk what, I want to improve the team but in the same time i dont want to waste money and tokens, what kind of players should I necessarly buy and which type I shouldnt? How I should organise the transfer window to be benefic?
What formations should I use, I know there are multiple answers on that but I would like to know which are the most used formations
And any guides ant tips would be welcome, any help, everything, would be great!
What about trainings?
