Super Falcons coach Edwin Okon has opined that his side&rsquo;s missed opportunities in Wednesday morning&rsquo;s Group D clash at the Women&rsquo;s World Cup cost Nigeria a spot in the round of 16.<br /><br />From one of USA&rsquo;s few opportunities, veteran striker Abby Wambach netted the match winner just before half time off a corner kick by Megan Rapinoe.<br /><br />&ldquo;It was a great experience for us here in Canada. We weren&rsquo;t focused enough in a few situations today,&rdquo; Edwin Okon stated in his post match comments published by the official website of Fifa, fifa.com.<br /><br />&ldquo;I wasn&rsquo;t surprised to see USA make substitutions that were more defensive after our sending off as they knew they were playing a good team. <br /><br />&ldquo;You always have a 50-50 chance in every game. Today USA made the most of one of their chances and we didn&rsquo;t, even though we had several.&rdquo; <br /><br />The African champions have advanced to the knockout rounds only once in seven editions of the showpiece event in the Women&rsquo;s football calender.<br /><br />Photo Credit : fifa.com<br />
