Gemma Davison scored a hat-trick as England women closed in on a place at Euro 2017 thanks to a second 7-0 win over Serbia in four days.
The Lionesses head Group G and are guaranteed a top-two finish, though only group winners definitely qualify.
Jill Scott headed the opening goal and Ellen White added a second.
Davison ran onto a backpass to make it 3-0 and added two more in the second half, her first three England goals, before Nikita Parris scored twice.
Like Davison, they were the first international goals she had scored.
Victory in Stara Pazova took England above Belgium - whom they visit in their final game after hosting Estonia.
The eight group winners and six best runners-up will join hosts the Netherlands in an expanded 16-team event, with the other two runners-up playing off for the final spot.
England also beat Serbia 7-0 in Wycombe on Saturday.
