Help and whats my chances?

Hi I think i have a good chance of having a go at the hat trick challenge tonight against a team in the champions league.
Im rated 62% higher..
I'm Still fairly new but i really want to go for goals.
any help on taking on a opponent playing 4-3-3
DL-DC-DC-DR
ML-MC-MR
ST-ST-ST

I know its not as easy as it sounds. but, i think its a realistic chance of getting a player 3 goals in a game.
any idea's how i should set a formation up?
Thanks.

Only league games matters for the challenge !

is it ! oh doh what a numpty i am.

In league games , after you score a first goal you might select that player to take penalties and free kicks also . It might work if it's an attacking player .

cheers buddy.
