Yes, it is. It's probably more positive because of financial implications than regarding the performance on the field, since Robinho will be around for only six months.
Brazil is finally putting it together in terms of football management and marketing. This means more cash for the clubs and probably more talent in our leagues. I hope this is not just a brief situation.
That would do wonders for the sport. It would be great for the development of new talents all over the world as well. Maybe the South Americans would slow down the production of great young players and Europe could catch up in that departament.
Yeah, plus it would see more competition between the different continents. It would also encourage clubs to produce their own homegrown talent instead of buying youngsters from different countries. The richer different leagues/teams get, the easier it will be for them to hold on to their best starlets.
Robinho knows how to do fancy stuff on the pitch. Here in Brazil we even mock him that he has great skills but it's not that effective, but unfortunally (it was against my team) he was pretty effective this time.
