Peterborough boss Darren Ferguson vowed to make extending striker Saido Berahino's loan a priority after seeing the teenager fire the club out of the relegation zone.
The frontman, borrowed from West Brom until January, put the seal on a 3-0 home win over 10-man Derby with two late goals after captain Michael Bostwick had set them on their way.
Ferguson said: "Saido is only 19 but he is already a very good player. He is intelligent, caused Derby problems all afternoon and fully deserved his goals.
"We have already asked the question about whether we can extend the loan to the end of the season.
"Saido is loving life here and Steve Clarke, the West Brom manager, knows he is being well looked after.
"We've won four of our last six matches and the players deserve an awful lot of credit for showing real bottle in a tough situation.
"Some people were already thinking we were down and out and there were a lot of tough questions being asked, but we have showed what we are capable of doing when playing to the right standard."
