It think the voodoo comment by Moshiri, is his way of trying, to get out of the whole scheme, with the skin on his nose.
In a way, he is making Lukaku a lesser person, by remarking on his african culture.
Im sure Moshiri has his own believe system, that many of us would find offensive, soo there you go.
What comes around, goes around
Tbh mate, I think Moshiri was just using the story as a way of showing just how mad the whole thing is, with agents, players, contracts, etc.
Basically, one minute they say one thing, and the next minute it's all changed on a whim.
