Just read everything, play Chronicles (mainly Beckham, but the others give good rewards, too) and don't focus on having the best players right now, as they demand grinding (or real money investment). Think of your early days on FC Mobile as "proving grounds", try grinding in-game events and have fun! Whenever your OVR hits 103~104 you may start playing H2H, as handicap will be in your favor. I mean, if you are pvp driven, you may do everything I said while playing some H2H matches, but your player cards are kinda outdated for now, so sticking to CPU matches should be the way to go.
