Frustrated Belles boss Gordon Staniforth said Fran Kirby gave Reading a cutting edge they could just not match after falling to their first FAWSL2 defeat.
The promotion-chasing Belles now trail Sunderland – who beat Aston Villa on Sunday – by five points in the league after hotshot Kirby’s hat-trick ultimately blew them away.
But Staniforth says his Belles can get back on track in rapid fashion against Villa in mid-week.
He said: “I’m very disappointed.
“We’ve been beaten by Fran Kirby really, she was excellent and it’s difficult to take in.
“We had a good start in the first ten to 15 minutes.
“I thought we played really well and took the game towards them but Fran’s got a hat-trick and really she’s won the game.
“I would call this a bad day at the office.
“As I’ve said to the girls, there’s not enough players that were seven out of ten or above to get a result out of the game.
“But the beauty is that there’s a game on Thursday (at home to Villa) so we can’t feel sorry for ourselves.”
As well as Kirby’s cut-throat hat-trick, the England ace also turned provider for the Royals’ fourth goal when she squared the ball to Bonnie Horwood who finished coolly in the left corner to condemn Doncaster to their first defeat of the season.
