Rovers came close to pulling off a major cup shock against the Women’s Super League side, who scored twice in extra-time to book their place in the fifth round, after Rio Hardy saw her spot-kick saved in normal time.
Rovers return to league action on Sunday, when second-place Nottingham Forest visit the Anchor Ground, and Donnelly wants to see a repeat performance.
“It will be another team game, against a team who are second in the table,” said Rovers’ interim manager.
“They beat us 2-0 at their place earlier in the season, but by all accounts we were quite dominant, we just couldn’t finish. It’s hard to compare games from earlier in the season, because there has been such a change in the team.
“It was an amazing performance from the girls last week. What we perhaps lacked in quality against Reading, we more than made up for it in hard work and effort. They just could not get through us.
“Had Rio scored it could have been a different outcome, however, on a positive note, it means that we have one thing less to hinder the remainder of our season.
“Taking the positives from that game into Sunday, again it’s going to be a big ask to get anything from it, but we’ve just got to be positive, work hard and just play our game. All too often this season we’ve concentrated too much on trying to counteract the opponents, it’s taken away from our strengths, so we just need to play our game and make life difficult for them.”
