Sunderland defender John O'Shea says the players must find stability in their performances after a mixed start to the Premier League season.
"Consistency is what we need to find, some performances have been so good, some bad," O'Shea told BBC Newcastle.
"We've got to find that level that we know the players are capable of."
The Republic of Ireland international continued: "There's no better opportunity than against West Bromwich Albion on Saturday to bounce back from a poor performance."
O'Shea has made three appearances for Sunderland following his July move from Manchester United for an undisclosed fee.
Meanwhile Sunderland's starting XI on Monday featured nine full internationals, with two more on the substitutes bench.
However boss Steve Bruce was left frustrated with an experienced outfit that failed to perform at Carrow Road.
"That's the disappointing thing, that Jekyll and Hyde thing, that 'typical Sunderland' tag is still coming back to haunt us," Bruce said.
"We've played so well 10 days ago [against Stoke], and although it was never going to be easy we can't expect to win a game with six or seven players below par."
