New to FM13, help?

Better late than never but finally got FM13 today.

Just started a season with Mansfield (team I support) Anywho 8 games in I'm struggling a bit, won 3, drew 5.

I know I haven't lost any, but something doesn't feel right.

Any help/advice on tactics or players, or just help/advice in general.

Any help much appreciated, thanks :)
