The Black Cats have lost their last four Premier League matches, and they have only hit the back of the net three times in these fixtures.
And with a contest against Liverpool next up this evening, Allardyce is hoping to see a greater ruthless edge to his side’s display.
He said: “One, can we find our frontmen to score when they get a chance, which has been thwarting us recently?
“And two, we have to get much more resilient defensively to stop leaking these goals particularly in the first 20-25 minutes.
“It’s not a difficult thing for anybody to work out what we have got to do.”
Sunderland’s four consecutive defeats have put them back into serious trouble.
The Black Cats had started to show signs of progression under Allardyce, but they have now slipped back into the drop zone.
Sunderland are seven points away from safety, and their recent displays have offered little encouragement.
Sunderland have been well beaten by Chelsea and Manchester City in their two most recent outings, and beating Liverpool will be a tough test.
The Reds have improved under Jurgen Klopp, and will move up to seventh place if they are able to win this evening.
