The injury thing was a throw away line, the main point was for him to come back and get game time. Focussing on one half of a sentence that obviously wasn't the point of it is in itself silly.
The people that say you have to go to Europe to succeed are just euro snobs. You can develop in the A-League and even get the eye of foreign scouts much easier than in europe because you actually get game time.
I'd rather be playing in the A-Leage 90 minutes week in week out than getting a few minutes here and there in Europe. It's not like he's getting lots of minutes in what is a pretty poor league by European standards. I could see the argument for being a bench warmer if your playing in England, Germany, Spain, Italy, France, Russia, The Netherlands, etc. But not if your a bench warmer in Switzerland, or in the 3rd division in France like Tuiolama then come home and get some game time.
Just look at young players like Bonevacia and Rodriguez who come from Europe to the A-League specifically to get first team football.
