After a second goal of the season for our Finnish striker, and a second clean sheet in as many games, City's women head into the break on fine form after a win at the CopperJax Community Stadium.
Rick Passmoor made five changes to the side that drew with Aston Villa in a stalemate last weekend, with Olivia Clark, Chantelle Swaby, Hlín Eiríksdóttir, Rosella Ayane and Rantala all coming into the XI in South London.
Rantala breaks the deadlock
It only took two minutes for the first goal to come in Bromley when Rantala fired in her second of the season, taking the roof off the Lionesses' net from close range with a left-footed effort.
Having found the target in the previous League D group stage game against Ipswich Town, Jutta doubled her tally on Sunday afternoon early on, which was enough to get the points on a wet and windy afternoon in the capital.
Another clean sheet
Even for most of the first half, London City were pushing hard for a way back into the game, ramping up the pressure in the final 20 minutes, but City's defence stood strong to earn a second consecutive clean sheet.
Having kept out Aston Villa to earn a point last time out, Passmoor's side are starting to earn a positive reputation, keeping out the WSL's latest competitors.
Two clean sheets, for two different goalkeepers, in two away games, will give great confidence to our Foxes who now jet off around the globe to join up with their respected nations for the international break.
Foxes on top
Seeing out a second win of the competition, Leicester sit top of Group D with the maximum six points, with only one game to go against Crystal Palace, to come in late November.
One point against Palace would be enough to see us top the group and move on to the knockout stages, as our immediate focus now turns to the WSL, when we welcome Arsenal to King Power Stadium after the international break.
