Why is the AI so much better at finishing?

[wwfan]

and why is there no answer for strikers missing so many 1vs1 against small teams? all i see is ppl saying go defensive, hell i even tried 4-2-1-2-1 (2DMS and 1 MC) with control mentality and guess what still conceed in a freaking CA because apparently 2 DCs can't mark 1 lonely striker that is between them 2 and 1 meter away from them. also why is every AI crossing in CA so perfect that always goes near the AI striker? i'm yet to see 1 crossing from CA go out,meanwhile dimaria,ozil,douglas costa,william,gaitan keep doing it...i'm starting to abandon wingers tactics, they all made stupid crossing that either go out or straight into keeper

Small teams will sit back and try to kill space deep on the pitch. How would you tactically go about overcoming that type of approach? Think holistically, rather than trying to work out what individual plays/formations work better in the ME.
