Ahead of the second set of UEFA Women's Champions League group games on Wednesday and Thursday we highlight four players who made impacts in their first appearances at this stage on Matchday 1.
Nicole Anyomi (Frankfurt)
Four-time champions in their previous guise of 1. FFC Frankfurt, Eintracht began their first group campaign with a 2-1 victory against Rosengård in Sweden. Now a home encounter with holders Barcelona awaits on Wednesday and Frankfurt will look for another excellent display from in-form Anyomi.
The 23-year-old Germany forward has been among the goals of late and although she did not find the net at Rosengård, Anyomi did set up Tanja Pawollek's opener and was a lively presence throughout her first game at this stage of the Women's Champions League. Her speed, strength and eye for goal make Anyomi a threat even to Barcelona.
Amalie Eikeland (Brann)
Brann are the only group contenders never to have previously been among the last 16 under any format, but the Norwegian outfit are already well-placed following a 2-1 win at St. Pölten. Victory at home to Slavia Praha would leave them in an even stronger position, with energetic winger Eikeland aiming to perform as she did in Austria.
The Bergen-born Norwegian international rejoined her hometown club (who were known during her previous spell as Sandviken) after relegated English club Reading released their full-time players in the summer. A fan favourite in England, Eikeland is now in her first Champions League campaign at the age of 28.
Rosa Kafaji (Häcken)
Paris FC, who raised eyebrows by knocking out Arsenal and Wolfsburg to reach the group stage, were given a taste of their own medicine on Matchday 1 by Swedish visitors Häcken, who claimed a memorable 2-1 win in the French capital. Playmaker Kafaji coolly took her chance to put the visitors ahead, adding to a fine year in which she finished as Häcken's top league scorer.
Having been an unused substitute in both legs of Häcken's round 2 defeat to Paris Saint-Germain last season, this is Kafaji's first European campaign on the pitch. Having also made her senior Sweden debut in October, the 20-year-old is making good the promise she showed as a teenager at AIK.
Sherida Spitse (Ajax)
The second most-capped European with 225 appearances for the Netherlands, midfielder Spitse has featured relatively little in the Champions League. Her round 1 penalty against Dinamo-BSUPC was Spitse's first goal in European club competition, while her second, also from the spot, helped Ajax to a stunning 2-0 victory over Paris Saint-Germain on their group debut.
The 33-year-old has long been considered one of the game's best from dead-ball situations. Her experience in a mostly young squad proved important on Matchday 1 and will be again on Thursday when Ajax visit 2022/23 quarter-finalists Roma.
