TIP:If you are not getting many chances, buy a player with high creativity or several forwards with high heading, and a decent corner taker. If you are getting chances but not converting them, buy players with high shooting and heading ability. Also specifying a player with high set piece and shooting abilities to take direct free kicks will help.

TIP:Every shot goes in : this tends to indicate a bad goalkeeper. Judging goalkeeper form is very hard and it may take a while to find a goalkeeper who will perform well.
Permanently under pressure : this tends to indicate that you have a weak midfield as opposed to a poor defence and that they aren't holding the ball up and giving the defence some relief. Try either packing the midfield with more players or switching to long ball tactic, if you are not already using it.
Poor defence : if you have few good defensive players, then try playing 532 with midfielders in the wingback positions and your best defender in a sweeper position in the center, usually he will mop up any strikers who get past your weaker defenders.

TIP:Make sure that you have an experienced (usually 24+) player with a high influence as your captain, if you haven't then your younger players may not perform as well as they might.
TIP:Choosing correct Free Kick, Corner and Penalty takers is very important.
TIP:Be very careful when purchasing Foreign Players as they are required to play in 75% of games to retain their work permits. If they loose their work permits then you will be stuck with a player in your squad who cannot play for you but is taking up a squad space.
