How can i improve in soccer?

hey, i need to improve in soccer. my coach isn't really strict and whenever we lose a game(all of them so far..) he says its okay. its my first year so i jsut started , but i've been doin aiight. i'm not the best, but im average. i'm a really good sprinter so i wanna be a center fwd, but i can never keep the ball. what are some tips like DRIBBLING and PING that'll help during the game and practice? i wanna show my coach that i can do really well as center fwd because thats what i started off as in the beginning because of my speed, but now im put everywhere.. :O
