The former Ipswich man has been a bit-part player since arriving in south London but Burley hopes his strike against Rovers can trigger a run of form.
Burley said: "Pablo Counago hasn't been a regular for us but we're working hard with him doing extra training sessions.
"He showed that it's worth it. He's not had any easy time the last few years and hopefully he can push on.
"Overall I'm very pleased to get a third win in four matches. We know Doncaster are a good passing side so we put an attacking team out to try and put them under pressure.
"We wanted to stop them getting any time on the ball at the back. It went very well, we stopped them playing their free-flowing football."
