Alan Pardew admits Charlton Athletic match-winner Svetoslav Todorov was not happy to start the derby with Crystal Palace on the bench.
The summer signing was left on the bench until midway through the second half and then took less than 10 minutes to grab the only goal at Selhurst Park.
The Bulgarian striker was disappointed not to be in the starting line-up, but Charlton boss Pardew explained his reasoning behind the decision.
"After recent results we've had to tighten up, so we sacrificed Toddy, but a little bit of quality came to the surface," said Pardew.
"The back four were stronger and we created a few openings in the first half. But in the second half we got a feel for the game and a great bit of skill from Toddy has won it.
"Toddy has his way of showing his displeasure at not starting - he gives me a strange look and walks around a bit sheepish. But there was no-one happier than him at the end.
"I've got an abundance of midfielders and strikers, lots of talent, so we are going to have to sacrifice players.
"We've done a job here today. We didn't open up and play like we would at home, but it was important to get our first away win. We don't deserve massive plaudits, but we've done a good job."
Eagles manager Peter Taylor was in no doubt where the blame lay for Charlton's winner, and insisted his side had deserved at least a point from the game.
"I don't think we deserved to lose, everyone has given their all, but we messed up for the goal big time," he said.
"If the goalkeeper comes out and calls for it he has to claim it.
"It's a bit like how we started last season, giving goals away. I don't expect us to concede goals like that.
"But people make mistakes and they have to bounce back. Julian (Speroni) has been as safe as houses for us."
