There's loads of info and tips here in the forum, but it can be a nightmare to find what you're looking for. So if anyone replies with a link follow it up.
Don't panic for the first few seasons. A managed 4 star team will win you things.
My 2nd team is at level 7 this season, won 5 leagues, 5 cups and a champions league, but, and here's the thing, it has over 1000 rest packs banked through watching videos and 500 tokens through finding a gold 1 association and not buying expensive players.
Take both academy players. The free one as cannon fodder in training and the token one pumped with greens to 5 stars will be cheaper than buying a player like him at auction. Selling the 0 token players is always good for a cash boost as well.
Don't watch videos to farm anything other than rest packs. Treatments, morale and money will find their way to fill your resources.
Find tutorials or guides here in the forum on how to train to get teamwork bonuses to 10% and keep them there. (Sorry I don't know where they are.)
If you're looking for an association check out New Team 2017. Gold 1 and we have 1 free spot. Spanish predominant language, but I'm in there as well.
Good luck.
