Adelaide United coach Guillermo Amor says he's a winner and an optimist - and that's why he's getting increasingly annoyed at a winless A-League season.
Amor's Reds remain the only club without a victory after losing 4-2 at home to Melbourne City on Thursday night.
"There were some good moments but there were some bad ones as well," Amor said after the loss.
"There were some mistakes which cost the team.
"I'm an optimist. I'm a winner. And it's because of this, these little things are making me annoyed."
Amor entered the clash with questions over his attack - they had only two own goals before the fixture - but at least they found the net via Sergio Cirio and Pablo Sanchez.
But the queries shifted to the Reds' defence which was repeatedly sliced open by City and has now conceded 10 goals in their three successive defeats.
Amor said defensive errors were a recurring theme but maintained confidence within his camp remained solid.
"During the week, the work they have been doing is good, they are confident before they go into a game and during the game.
"The attitude is good, they are working very hard."
