I've heard from two football players the same age as him that they were very very surprised he's been signed and didn't rate him at all. Hope he proves them wrong! with Reid and Smith we have a plenty of potential in defence for NZ, hopefully Musa can add to that.
Musa does the basics right and have a far better football vision than most. I don't know about other young footballers but what I briefly saw of him, he did everything in the game that had real football sense and not many players that I have seen has that sense at such a young age.
I can only imagine that other young footballers may have underestimate/not understood why Musa does what he does and only look for extraordinary skill/trick when the best option is simple football. He is composed on the ball and makes the right passing options and also able to accurately pass the ball to set up a phase of play. Playing against him is one thing, but if you look on the overall game, he does the simple, basic and effective things that most footballers struggle to do.
Not many youngsters stand out to me as he did. The fact that he understood what he was doing showed me that he had a mature football mind already.
