England came away from Greece with a crucial lead in their 2027 Women's World Cup play-off tie but will rue numerous missed opportunities to build a bigger advantage.
It was not a convincing performance from Sarina Wiegman's side and they conceded in the second half, which gives Greece some hope for Tuesday's second leg in Leicester.
Ioanna Papatheodorou was the home side's biggest threat and she struck the crossbar in the first half before teeing up Kallisti Brouksair for the hosts' goal after the break.
That stained an otherwise improved second-half performance from the Lionesses, who were pedestrian and unconvincing in the opening 45 minutes.
Arsenal midfielder Georgia Stanway broke the deadlock just before the interval before Maya le Tissier and Alessia Russo extended patient England's lead in the second half as Greece started to tire.
However, a lapse in concentration defensively allowed Brouksair to fire home.
Manchester United captain Le Tissier took her chance to shine in the absence of the injured Lucy Bronze and was the standout performer at right-back.
There were flashes of quality from Chelsea forward Lauren James, who nonchalantly lobbed goalkeeper Fafailia Petaloti from 30 yards in the first half, but her effort was ruled out for offside.
Further opportunities came Lauren Hemp's way, while Beth Mead struck a shot wide - but the results means there is still work to do for the back-to-back European champions.
England remain heavy favourites to progress to the second round of the play-offs, which will determine who qualifies for next year's World Cup in Brazil, but they must finish the job at the King Power Stadium on Tuesday (19:30 BST).
Should England qualify for round two, they will play either Ukraine or Slovakia. Ukraine were also 3-1 away winners in Friday's first leg.
