Brighton manager Gus Poyet was delighted for Stephen Dobbie after the Scottish striker came off the bench to give his side their first win in eight matches.
Former Blackpool and Swansea man Dobbie opened his account for the Seagulls in stoppage time as Brighton downed Peterborough 1-0 to record only their third win in the last dozen home games.
Dobbie's chances have been limited, with eight of his 10 appearances coming as a substitute, and boss Poyet said: "He has showed what he is capable of. I told him when he came on that this was his chance. We needed quality and he delivered it.
"Hopefully Dobbie will now relax and make it more difficult for the manager. The way football is nowadays, we don't wait for people to adapt. We want a hat-trick from new players straight away.
"Stephen had two or three chances when Craig Mackail-Smith was out injured and he didn't score, but it's not that easy. Obviously he wanted to score as soon as possible and I am delighted he is now off the mark."
Brighton had drawn four of their previous six games and Poyet admitted: "I hope this win can be a turning point. It's up to us.
"We have got two difficult away games now (Wolves and Huddersfield) and we must keep believing.
"In the second half it was all about us. We had 32 shots and scored one goal. But the key to it was we didn't concede a goal so we won the game. If you don't concede it gives you the chance of winning."
Peterborough were on course for their first draw in 15 league games when Dobbie, who replaced Andrew Crofts in the 64th minute, latched onto a pass from Ashley Barnes to chip over keeper Robert Olejnik, and manager Darren Ferguson said: "Unfortunately we didn't quite see it through.
"Brighton were a bit relentless in the second half, we didn't keep the ball well enough and unfortunately we lost it at the end."
