The Scotland international made an instant impact after being subbed on in the 74th minute as she scored a world class strike to help City beat Manchester United 1-0.
In a tight fought game it was going to take something sensational to break the deadlock and Weir produced, picking up possession 35 yards out and chipped United ‘keeper Mary Earps from the edge of the box.
It was a Derby Day goal to remember for everyone apart from the player herself!
“I actually don’t remember too much! It was a bit of a blur,” she said.
“I can’t help but try it.
“I try it all the time in training and sometimes the keeper catches it and I look a bit silly but sometimes it goes in and luckily today it went in.
“It’s about picking the ball up in those areas and trying to make the most of it.”
The victory means City closed the gap to just two points on third placed United.
And while Weir was delighted with her goal, she knew the victory was the most important.
“We needed those three points so I’m delighted for the team,” she added.
“We needed to win, we couldn’t draw.
“We knew how important it was and we need to carry this momentum as we go.
“I think the whole team played well today and we’re delighted to get the win.”
