Ashley Robinson felt the Corby Town players “did themselves proud” despite suffering an early exit in the Southern League Challenge Cup.
The Steelmen made wholesale changes to their starting line-up for the preliminary round clash with league rivals Peterborough Sports and eventually slipped to a 3-2 defeat.
The hosts opened the scoring through Zac Allen only for former Steelmen captain Paul Malone to bring Sports level before the hosts took the lead just before half-time through Andre Williams.
That advantage was extended to 3-1 thanks to a goal from Jordan Brown and, although Corby pulled one back through Greg Ling from the penalty spot, the visitors saw things out to move into the next round.
But asssistant-boss Robinson was pleased with what he saw from a makeshift Steelmen team.
“We used the whole of our squad,” he said.
“We have got a big squad in terms of using the young lads and it was about seeing them and working out what their strengths and weaknesses are and seeing what we can work on moving forward.
“But I thought each and every person did themselves proud. We moved the ball very well and we were unlucky.
“It’s given us a headache now when we have to pick a team on Saturday.”
The focus is now on a return to league duty as Corby look to maintain their unbeaten start in the Evo-Stik League South Division One Central when they head to North Leight at the weekend.
Robinson is set to take charge of the team with manager Steve Kinniburgh away while he takes his coaching badges.
And the assistant-manager added: “We want to keep the momentum going.
“We have got a fantastic group of lads and I am looking forward to it.
“It’s a big challenge, a big game away from home but we have nothing to fear.”
