Mick McCarthy has stressed the need for Wolves to start keeping clean sheets if they are to climb out of relegation trouble.
Wolves halted a run of four successive defeats via last weekend's 3-2 home success over Sunderland but they remain in the bottom three and McCarthy knows they have to tighten up at the back.
He said: "Last weekend was just reward for the work we have put in. We played well, got that little bit of luck and want to build on it. But we need to keep a clean sheet and not concede the type of goals we have been doing."
He added: "The win over Sunderland was the first time we have scored three times at home in the Premier League.
"But we can't afford to concede two goals because we aren't going to win too many matches 3-2."
McCarthy, whose side visit Blackburn on Saturday, believes good fortune may be starting to turn Wolves way after playing well in recent weeks without earning any tangible reward.
He said: "I've said all along it will turn for us. We had a bad run and you have bad runs - as a player and a manager.
"We've had a bad spell in terms of results but not in terms of the way we have been playing.
"We had that bit of luck against Sunderland with them having a shot hitting the inside of a post and bouncing out plus us scoring a goal that was offside."
