Coach John Kosmina has written off Adelaide United's 6-1 A-League loss to Western Sydney Wanderers in the hope it's an aberration.Kosmina says there's no point dwelling on last Friday night's horror result for United, partly because his club doesn't have the time, with a looming home match against Brisbane on Wednesday."There is not much you can do after an outcome like we got last Friday night," Kosmina told reporters on Monday."We talked a little bit before training about the why's and wherefore's but sometimes you just get those games where nothing you do turns out right."Partly it was our fault and they had a lot of good bounces of the ball as well so we put it behind us ... because we haven't got time to dwell on it."The Reds host Brisbane on Wednesday night at Hindmarsh Stadium but Kosmina said he would put little emphasis on the struggles of the defending champions."It's not so much about Brisbane, it's about us," he said."We need to get back from that result on Friday, if we can get a good positive outcome here on Wednesday, then Friday doesn't matter that much any more."We all have to be tuned it, it's more about how we respond to what happened on Friday."Kosmina hinted he was reluctant to make sweeping changes in the wake of the heavy defeat to the Wanderers."You can take the gloom and doom aspect of it and start making changes ... (or) do you keep the changes down and say 'look, here's another crack at it but it might be your last one'," he said."I have tossed up a couple of ideas but we will make a final decision tomorrow."Meanwhile, Kosmina also supported Football Federation Australia's ban of an Adelaide United member for racially abusing Wellington Phoenix star Paul Ifill eight days ago.The spectator was banned for two years with the Reds also cancelling the man's membership."It had to be dealt with quickly and harshly and they have got to the bottom of it," Kosmina said."And the person concerned is not going to come into the stadium for a couple of years because what was said was unacceptable."It's how it should be."
