firstly give him time to settle in, he does not know english and does not know premiership (beleive me its true) it does make a huge difference.
secondly play him alone, with good pacey wingers and a creative midfield!
set him as target man and set your pacey wingers as playmakers.
i have a tactic that i use 4-5-1 attacking mid AMC and works really well!
give him attacking full, freedom - half and rest half everything, passing on short, so he can play one two's with the AMC
