On arrival after two weeks, promising Umotong got her first taste of action almost immediately as a late substitute in a warm-up 1–1 draw against a male academy team, showing true dedication in her quest to make the team for Canada 2015. She followed it up with a goal when she came on for 20 minutes in another tune-up match against Nigeria Women Premier League side, Confluence Queens, before becoming the first Portsmouth player to feature in a full international after making her 33-minute debut for Nigeria in the first leg of their All-Africa Games qualifier against Mali in Bamako. She was eventually named in the 23-player list for the World Cup in Canada but did not feature in any of Nigeria's three group matches as the African Champions failed to progress to the knockout stage.
