Oldham boss Paul Dickov heaped praise on striker Matt Derbyshire after his side beat Doncaster 3-1 in the FA Cup second round on Saturday.
Derbyshire, on loan from Nottingham Forest, ended a nine-match barren run as Oldham turned on the style following Reece Wabara's glancing header to cancel out Robbie Blake's opener for Rovers at Boundary Park.
Dickov said: "I'm delighted for Matt because he has been working ever so hard without getting the rewards.
"He has been frustrated, but we've been telling him to keep going and keep getting into the right positions.
"He has deserved those goals and he's such a good player that it was always going to happen eventually.
"As a team, once we got our front players more involved we caused Doncaster all sorts of problems.
"It took a while for us to recover from their goal, but apart from the first 20 minutes it was a magnificent performance.
"We got players into their box, we kept going forward and some of our attacking football was fantastic.
"We all knew the importance of this game because having a decent cup run can make a big difference financially to a club like ours.
"Doncaster are one of the best teams in our league and they've been on a good run, so I'm delighted with the result."
