I simply cannot get my head around why someone that has got to ManUtd reserves would move here to play for an amateur team. Bizarre.
Maybe it is not quite his plan. It is also his off season, so he could keep his off season fitness going having only played 12 matches for the ManU reserves.
At least he has his international clearance sorted and a winter club to play until any NZFC or A-League season starting up. However he is in Wellington and playing football, which means he is here for the while.
After having been at ManU since 8/9 years old, maybe he would like an good OE break away from the very high competitive club environment. He is still 19 years old and with a bit of oversea experience elsewhere, he could make a name for himself.
If he does well at A-League, he would be in the sights of many EPL/Championships clubs who would have noted his youth career. Many reserve and youth players even at the top clubs don't have that much exposure to first team managers of other clubs, so he maybe thinking outside the square. Either play a couple of years in the Reserve PL and not get noticed or play in another english speaking country's league which has a new professional league with TV coverage that would open doors.
As I see it, A-league opens doors for top flight youth players trained at top clubs looking for exposure or for players at the end of their careers making hay while the sun still shines. Plus having soccer in this part of the world while the northern hemisphere is having an off season is very much the right time for him to keep his football going. It's that type of league at the moment.
