(50/10) x (25+75) + 3
Couldn't figure out how to incorperate the 100...
Back on topic, I read Martinez comments on the official site regarding Henen. Unless there is more that hasn't been posted he's talking like he has already signed:
Martinez said: "He's a young, talented footballer who represents Belgium in the lower teams, in the Under-18s and has had good experience in going to France.
"He is a bright boy and we feel he is something different that we haven't got in the Under-21s, so we are hoping he is going to be giving us something different in that group.
"We want a strong group. We have already got talented and very interesting footballers and I think David can fit in really well in that environment."
