Chelsea were held at Bristol City as the defending Women’s Super League champions began the new season with a second straight goalless draw.
Switzerland’s Ramona Bachmann dragged a shot wide before hitting the bar as Chelsea went close in the first half.
City keeper Sophie Baggaley then denied Bachmann with a good second-half save.
The result left both sides unbeaten in the league this term, with Bristol City having picked up four points from two WSL games under new boss Tanya Oxtoby.
On the ground where they won 2-0 to clinch last season’s WSL title in May, Chelsea dominated but were unable to break the deadlock.
The match was the Blues’ fourth in 10 days in all competitions since opening their campaign with a 0-0 draw at home to title rivals Manchester City on 9 September.
Bristol City boss Tanya Oxtoby told BBC Radio 5 live sports extra:
“That’s our second clean sheet now in the league and we have been working at that so I’m super pleased. The girls have worked really hard tonight.
“Structurally, we were really hard to break down tonight. That can be frustrating for the opposition.
“With the team Chelsea put out, they showed us a lot of respect. They knocked and knocked, but we were quite resilient.”
Chelsea manager Emma Hayes added:
“Credit to Bristol City. Ultimately we did not create enough chances inside the penalty box for us to come away with the win tonight.
“That’s how teams are setting up this year – if you’re not one of the top three or four teams – with five at the back. It is a tricky place to come down here.
“It is difficult to retain successive titles. Everyone gets hungry and more organised.
“We are just going to have to be in a chasing position this year and make sure we put ourselves in the best position for that first win.”
