The Matildas have downed Chinese Taipei 7-0 in their first match at the East Asian Cup women's soccer qualifiers in China.Kate Gill opened and closed the scoring for the Matildas, with her first goal coming in the fifth minute and her second in the 90th minute at Shenzhen Stadium on Tuesday.Lisa De Vanna and Kyah Simon both also scored twice and Servet Uzunlar scored in the 77th minute.The score line reflected the Matilda's dominant display, with debutant goalkeeper Mackenzie Arnold largely untroubled throughout."I'm happy with the win and happy with the way the players went about the game plan that we set out for them," Matildas coach Tom Sermanni said after the match."I'll give credit to Chinese Taipei, we thought they may have come out and really set up an eight player defence, but they came out and actually tried to match us and tried to play."Getting two early goals really relieved the pressure and I was delighted the way the players saw out the 90 minutes."Gill - whose match opener was her 11th in internationals against Chinese Taipei - was on hand to head home a precise centre from Samantha Kerr.De Vanna showed her quality in cutting in from the left wing to slot her first goal on 22 minutes, before Simon rounded out a solid first half show with a clinical tap in after Uzunlar's long range effort was parried into her path.De Vanna added her second only minutes into the second half, before Uzunlar's rare goal 15 minutes from full time.Next, Simon netted the goal of the evening - a right-footed strike from outside the penalty area that curled into the top corner, albeit after a fortuitous bounce off the post and the Chinese Taipei goalkeeper.Gill became the third player to net a brace when turning in substitute Katrina-Lee Gorry's cut back in stoppage time.The Matildas will next play Hong Kong on Thursday, and then China on Saturday.The team who win the qualifying tournament will join Japan, South Korea and North Korea in the women's East Asian Cup, to be held in Seoul from July 20 to 28 next year.This is Sermanni's last event in charge before he takes up the head coaching job with the US women's team next year.
