Reading boss Kelly Chambers called her side's performance "spot on" after they thrashed London Bees to top WSL 2.
England's Fran Kirby scored five of the Royals' goals in a 7-0 victory, taking her tally up to nine for the league season after just two games.
"It was a fantastic performance," Chambers told BBC Sport. "It was important we didn't concede today."
Elsewhere in WSL 2, Everton rescued a late 1-1 draw at Millwall, while Durham beat Oxford 3-0.
Reading's Bonnie Horwood and captain Lauren Bruton added to Kirby's five goals, the latter scoring from the penalty spot.

"It might come down to goal difference at the end of the season, no one knows," Chambers added.
"The girls set themselves the target of a clean sheet and they achieved it."
London Bees head coach Julian Broomes told BBC Sport: "I'm very disappointed with the result and even more disappointed with the performance of the 11 that I picked today.
"We've been struggling all week to field a team because we have so many injuries but that is no excuse."
At the Den, Chelsea loanee Rosella Ayane, making her Millwall debut, opened the scoring before Everton substitute Jess King grabbed a late equaliser for the visitors.
"It's disappointing for us to concede so late, but it's a really good point," Millwall boss Dan Mlinar said.
Everton head coach Andy Spence added: "We expected to put on a much better showing than we did. I can't honestly say we deserved to win."
Meanwhile, goals from Rebecca Beech, Amelia Pereira and Courtney Corrie saw Durham win at home to Oxford.
"It's a great start for us in the league," Durham manager Lee Sanders said. "We have to be happy with that."
Oxford United manager Les Taylor added: "We had three or four who were a little off today.
"That's a little disappointing."
