Doncaster boss Dean Saunders said his side's victory masked a poor performance after they hit back to beat Brentford 2-1.
Brentford dominated much of their visit to the Keepmoat Stadium on Saturday and carried a 1-0 lead into the break after Jonathan Douglas had clipped home Adam Forshaw's through ball, but a 25-yard stunner from Rovers winger David Cotterill levelled the League One game with 15 minutes to go, sparking Doncaster to life, and the hosts sealed the win with a powerful header from Billy Paynter.
Saunders said: "That result has papered over the cracks and there's a lot of work to do. It's a new team and I hope they just keep winning until we sort everything out.
"We dug in, showed some real desire to get the points and scored two great goals. But I have to say on reflection, they can feel hard done by that they've got nothing from the game."
Saunders revealed he has lined up a Premier League defender and hopes to complete a loan deal before the trip to leaders Tranmere on Tuesday night.
He said: "I've had to act because we've got problems at the back. Rob Jones played with a dislocated thumb, Shelton Martis went off injured so I've got to do something because I didn't have a defender to put on the bench."
