1- 4-3-3 that's for me the better, I have 22 players, to do 2 formations of 4-3-3, so with 6 MC's and 6 ST's one can see perfectly the differance of effecitveness.

2-depend... usually keep the same level. The game never show the 11 names of the players during a match, so, depend, and, that's the situation, and, that's why I always say that if you don't see the name of a MC/ST during 50' of game, you have to change this for another,.

3-play with that, you don't have to train all team always, you can train for example 1-2-3 young players that, train fast, 1 day yeah, 1 day no, and depend of -if you play, 1,2, or 3 competitions. Of course if you leave the cup, and fight for League and Champions League, you can play with the rests.

4-Because..¿?... you pay the salaries?... but you have the contract..nope? if you signed the contract you have to have money LOL

5-The stadium capacity... the grass...(better field to have (-)less injured players) and well... hospital... to have red treatments, and academy is too what I build usually... the interesting is to recive greens faster too... so... at the end the important that you have to know is that never have to waste tokens for the stadium.

Here my opinion
