Playing online has more returns. For example, winning an online division will see you earning around 5-10k depending on which division you are in. And the fastest way to earn coins is to do trading. Know the value of a player, buy low in the morning, sell high at night. For instance, during the TOTS season, players will be spamming packs, causing the market to be flooded by players who are selling their cards. This will cause the player's price to drop, drastically I would say. After this period, the price will return to normal.

So far, players are now at the lowest of value. As I've said before, always find the proper value of the player before buying them. Use websites like www.futhead.com to scout the value. I bought SIF Maicon for 23,000 coins, sold him for 40,000 the week later. Certain players will rise in value depending on the special cards that they get. I bought Martinez for 600 coins, rare gold player. When his TOTS card came out, I sold him for 3.5k. 

Trading is the easiest way to earn coins. You lose some, but you can gain more. At times I will sell at a loss, like selling Rooney for 30k when I paid 50k for him. But I can always earn back those coins by trading more. Hope it helps 

Start with cheap gold player ...average 300 to 750 ~

Which league or nation you prefer ?

you play 1 match can get average 400 coins easy   

I think it is based on the team star rating as well, but not chemistry.

And also, sometimes you need to mentally prepared. Yeah sometimes we feel that the game is against us. But in reality, our rage and urge for "must win this game" consume us, thus make us play poorly.

Just relax, play as you like and be awesome. The guide that I posted have step what can you do and I did follow the guide and some seems working. (like playing defensively and wait for opponent to make an error).
