Sweden coach Peter Gerhardsson said his “in-form side” are convinced they can knock the United States out of the Women's World Cup after setting up a last-16 tie with the holders this weekend.

A Rebecka Blomqvist header and an Elin Rubensson penalty gave a much-changed Sweden team a 2-0 win over Argentina in Hamilton on Wednesday as they topped Group G with three wins out of three.

The world's third-ranked team will now head to Melbourne to play the USA on Sunday, after the reigning world champions stumbled out of their group in second place with just one win.

It will be their first meeting since Sweden beat the USA 3-0 at the Tokyo Olympics two years ago on their way to taking the silver medal.

"We have played really good group-stage games, we have won all three of them, and we also beat them in the Olympics," said Sofia Jakobsson, who came into Sweden's line-up against Argentina and set up the opening goal.

"We are a confident team and looking forward to playing these games where it really matters and you have to win to move forward."

Sweden, who came third at the 2019 World Cup, had already secured a place in the knockout phase before their final group game by thrashing Italy 5-0 last weekend.
