It was the first time in the club’s history that they have recorded back-to-back clean sheets after getting their 0-0 draw against Melbourne Victory in Round 1.

Sarah Willacy was once again one of the top players on the field with the 159cm tall goalkeeper ensuring her side left with the three points. 

Adelaide coach Ivan Karlović praised Willacy for her role in the game.

"Sarah is a fantastic player and I think people underestimate her because of her height but she's probably one of the best keepers in the country," he said.

Not only was it the first time Adelaide had defeated Roar since November 2015 but their best start to the season since the 2015/16 where they were undefeated in their opening three matches. 

Adelaide have tended to hit form in the back half the season as the team spent more time together but this season pre-season went differently.

"We got the foreign players in a little bit earlier along with the interstate players and have had a little bit more time to prepare for the season," said Karlović.

"In the off-season, we have been able to get out local girls to be at a better level coming into pre-season so that obviously helps trying to get a better benchmark," he said.

Adelaide is one of the only teams besides the Western Sydney Wanderers to not make the finals series with their highest ever finish being fifth in the 2015/16 season.

Adelaide face Canberra United in their first home game of the season at Coopers Stadium from 7pm (local time).
