UEFA Women's EURO 2022 is under way and the groups are taking shape.
We pick out four players with key roles in the second set of games.
Lucy Bronze (England)
England needed cool heads in the cauldron of Old Trafford for the opening game. And, in former UEFA Player of the Year Bronze, they had just that as the right-back patrolled her flank, supporting Beth Mead in an area where the hosts dominated Austria on their way to winning 1-0.
Now comes Norway, and Bronze's nous will again be crucial, especially when her new Barcelona club-mate Caroline Graham Hansen switches to the left. Bronze is closing in on 100 caps and is the world-class talent England need if they are to break their major tournament hoodoo.
Grace Geyoro (France)
A training injury last month seemed for a moment to have deprived France of Geyoro, but she was able to take her place in midfield for her 50th cap on Sunday against Italy and produced a history-making first-half hat-trick. Even without that, her presence was a huge boost for Les Bleues as Geyoro is crucial to making their play tick in the middle.
Against a Belgium team with plenty of attacking threat, France will want to keep their opponents under pressure, just as Iceland managed in the Red Flames' opener. And Geyoro will be the link to giving France's exciting front three plenty of opportunities to get the second win that would ensure progress.
Lina Magull (Germany)
For the first time since the group stage was introduced, Germany did not begin as reigning champions or necessarily among the top favourites, but many are tipping them now after dismantling 2017 runners-up Denmark 4-0. Playmaker Magull was the heartbeat of that performance, winning the ball to score the opener and keeping Germany on the front foot.
Germany return to Brentford on Tuesday to meet fellow Matchday 1 winners Spain, and Magull's touch will again be needed if her side are to pin back opponents who can be rampant if not put under pressure themselves.
Vivianne Miedema (Netherlands)
It is fair to say few eyebrows were raised when Miedema put in a superb individual performance to ensure the holders came from behind to draw 1-1 with Sweden on Saturday, her country's all-time top scorer making the equaliser for Jill Roord to leave opposing coach Peter Gerhardsson lamenting "She is just so skilful."
Netherlands coach Mark Parsons freely admitted turning to Miedema for her thoughts as they sought to turn the game, but her main talking was done on the pitch as she often dropped deep to act as playmaker, something she has also done increasingly effectively at club level. Portugal have their work cut out keeping her quiet on Wednesday.
