I saw this & took this with a grain of salt. However, we complain that the A-League does not promote, here we have the A-league promoting.
This is the first player signing that I have seen on mainstream TV for the A-League this season, so already this is a good thing.

Douglas Costa is a seriously good player, I saw him a lot when the great man Ronaldo was playing with him in Juve, he is a serious baller, that was only 3-4 years ago

The fact that at 33 years of age he is in the A-League does show that yes injuries, attitude, commitment maybe not there, who knows. Will he succeed or fail, I certainly don't know as some of you posters (not you TSF), who are all already calling him a failure. All I know for a fact is some of my mates are now interested in coming to SFC to see him play, whereas last season even with free tickets I couldn't get them to come.
Now if Dustin Martin does sign for Manly Warringah Wolves for next season Sydney AFL would I go & watch, don't think so, I would go WHO?
The beauty of A-League off Fox sports, I now have no Foxsports, but Stan, Optus & Paramount & proud to say I cannot tell you one AFL player.
