If Ben Arfa is the #10 I can see Sissoko working just fine alongside Cabaye instead of Perch/Tiote. Think Moussa would be wasted on the wing though.
He'd be wasted there all game, but mixing it up behind Cisse would be a good thing IMO. He can potentially do some damage cutting in from the wings as we saw glimpses of it v Chelsea, but yeah, wouldn't want him stuck out there constantly.
