Wednesday’s 2-0 defeat at Chelsea brought up the century against her former club with the tenacious striker close to marking the milestone with a goal on a couple of occasions during the first half.
It was an opening 45 minutes packed with promise against the title chasers and Williams reckons the performance was a sure-fire sign of Blues turning the corner after a tough start to the season.
“In the first minute Stan [Lucy Staniforth] put in a great ball across the box that just skidded away from me in the wet,” said Williams.
“We rattled them in the first 45, they nicked a goal from an error and that just goes to show you cannot fall asleep for a second against top teams like Chelsea because they will be on you.
“They worked it better in the second half, worked out what we were trying to do and dropped off a little bit, they started playing it around and opening up the gaps.
“They made it hard for us and well done to them, they deserved the win.
“We said afterwards that it was an improvement, though. We had a lot of players out before Christmas, I was in and out and we had to bring in Academy players.
“There was some rocky form but it was testament to the girls that we dug deep. We want to keep improving because Birmingham is a great club and we have to keep proving that season after season.
“We lost the Manager and some players but we pull up our socks and crack on, that’s what we do.
“There are a few games in hand and we will look to win those and finish as high as we can in the table.”
It proved third time lucky in one respect with Williams having missed out on the 100 when fixtures at Liverpool and against Brighton got postponed over the past two weekends.
“It was last week that I thought I would get it and the game got called off again but everyone has been getting in touch to say congratulations,” she added.
“At first it was a bit of a surprise to me because I didn’t know how many I had played, someone sent me something on Instagram so I was delighted to finally get to play it.
“You just keep playing and I don’t think I am ever going to retire, I just love it.
“It will be the game that retires me, injuries or if age catches up with me, but I am happy to have made 100 appearances and am looking forward to making many more.”
Next up for Blues is a crunch clash at home to Bristol City, who sit a point behind Marta Tejedor's side, on Sunday 23 February at the SportNation.bet Stadium (2pm kick off).
