Firstly, zonal marking and a pressing style rarely mix. I've tried this and it worked in one game, but was disastrous in others with it conceding a stupid amount of 3 to Bolton with Man City. Also, a direct style can often lead to you giving the ball away too easily (as a few people have mentioned) so perhaps play a shorter game with a slower tempo (tempo isn't that important).
You're attacking down one flank and conservative on another; easy to defend and attack against. It's likely that the computer is targetting the side on which you're attacking down (i.e. your left, with full back and winger on attack duty). And equally, your opponents are more cautious this side, knowing that the other side isn't very attacking - either attack on both wings or on neither!
As aforementioned, your two centre mids are (currently) Fabregas and Arshavin, not the most defensive, eh? I'd certainly recommend putting Arshavin on the wing and play with a defensive midfielder or two who have high attributes in tackling, marking, positioning and work rate.
These few simple tips should tighten up your defence and benefit your team all round.
