Really, really dislike this type of thinking, pure eurosnobbery.... ultimately players should be reviewed and evaluated own their own individual performance rather than "ok yep played EPL, tick, lets pick him." Chris Herd, Con Blatsis, Nicky Rizzo, Richard Garcia and countless others all examples of players who got EPL action at a young age and showed that it means absolutely squat. Some of these were ok players like Herd and Garcia but judging from their EPL involvement at such a young age it was deduced that they would be stars but it simply didn't eventuate. Using simple logic we could say "ok well, Watts has played an EPL match now, but Robertson hasn't, so Watts must be better and must be picked over Robertson." The reality is a players ability shouldnt be judged by that given the myriad of factors at play ... for instance Southampton  has a lot poorer squad quality than City and also Southhampton currently has a huge injury list so it's a case of right timing for Watts. The fact of the matter is though that Robertson is highly touted by many who have seen him play in england wheras apart from the Austrialian junior setup no one is touting Watts, he's a squad filler at current. 

Great news rapt for the kid but let's not get too carried away yet. 

A first team game for an EPL team should justify Australia U23 selection, no doubt.
