Peterborough boss Barry Fry praised teenage goalkeeper Luke McShane, who starred on his debut in their 2-0 FA Cup victory over Milton Keynes Dons.
McShane was called into action just 10 minutes before kick-off after Mark Tyler injured his back in the warm-up.
"Luke did very well and made some good saves," Fry insisted.
"The lads in front of him protected him and restricted Milton Keynes to long-range efforts. We could have been three or four goals up at half-time."
