On a different, non-vaulting, note:
we should really consider buying his brother Jordan. He's a left-footed defender who likes nothing more than have the entire flank to himself to run up and down. At the moment he's playing for a modest Belgian team, Oostende. They are currently third in the league, and he has one goal and 4 assists in 15 games (as a left back).
He has massive potential although he hasn't (yet) shown the dedication and focus of his brother.
But I believe he can really contribute to this team AND we get to hav Romelu for at least another year. In a recent interview he stated again that his biggest dream is to play with his brother in the same team so that they and their mum could live in the same house again.
It would be a win-win situation: we get a good physical and technical (attacking) defender, Romelu stays another year and they are both happy. And what a happy Romelu can do, we see this year.
