Regarding new users, raising the initial budget will help a lot. I'd even go further and start a new club from scratch, i.e. no players and no arena, but with significantly higher cash to allow to build an appropriate arena and start with either good players or good trainees. Anyway, it will be up to decision of a new user how he'd like to start with his team, where to invest more (arena, quality players or good trainees) quiet a challenge for a new user.
