Yeah, I watched the whole series, there were probably thousands of boys there who tried out, pretty good ones too, so I imagine you'd have to be pretty special to win.
They sacked Kosmina, because Sydney are like Real Madrid, they're supposed to be the glamour club. If they dont win the championship then its considered a disastrous season. There were also reportedly some big rifts between him and some players. Also because Kosmina is a controversial character, who doesnt really represent the club well and has little to no respect for the opposition. Check this out:

Either way, if you look at the most successful clubs, Melbourne, Central coast, and Adelaide, they've all had thier off seasons. Its impossible to completely dominate the competition because its insanely tight. Theres little consistency in the A-league
Melbourne finished 7th in thier first season and the Melbourne fans wanted Merrick sacked, but the club kept faith with him; the next season he dominated the competition and thrashed Utd 6-0 in the grand final. They had another off season last year, we didnt go so well in the champions league, but this season we're officially the most successful club having won 2 premierships, 1 championship and the pre season cup.
And dont forget about Aurelio Vidmar. Adelaide finished 6th in 0708, but the owners kept faith and he lead them to the club world cup the championsleague final and now the finals series, so the key to success in the A-league is stability.
