Power rankings players

[tomy31]

Hi, i'm level 2 and i have some questions :

- i have some players with 3 or 4 stars, and i decide to buy players with 5 stars... but in match, my new players with 5 stars don't have better note than the others... They have average 7 , like others... there are in good place, total form, i don't understand... a player with 5 stars (average 26) not better than 4 stars (average 20) ?

- in transfert section, i can only buy players with average maximum 29... It will be always like that in future ? i see players against me with 7-8 stars!! only training or staff search for having that ?

- finally, i have some players with 4 stars and a masked talent (dribble etc...) , are they better than player with 5 stars with no talent ?

- i have some players 4 stars average 20 at 1.50M et my players 5 stars ...400K ... nomal ?

Thanks you for answer.
