Norwich striker Steve Morison claims his team must cut out the red cards if they are to have any chance of avoiding the drop.
Despite playing some good football in their opening three games, the Canaries have taken only two points and find themselves 15th in the table.
The Welsh forward says they only have themselves to blame after dismissals in their previous two matches.
In their first top-flight campaign since the 2004/2005 season Norwich could have beaten Stoke, but with 10 men on the pitch conceded a 95th minute equaliser.
And a week later having put Chelsea under a lot of pressure, they had goalkeeper John Ruddy sent off and collapsed to a 3-1 defeat.
Morrison said in the Daily Star Sunday: "We have been very pleased with our performances. There's been nothing disappointing about them at all.
"But we haven't won a game yet and that's something we need to put right as soon as possible.
"Firstly we need to stop getting players sent off. That would be a start. Then we need to stop conceding goals.
"Conceding late to Stoke wasn't nearly as bad as getting nothing out of the Chelsea game. At times we played them off the park.
"It's important that we win our home games because that is what will keep us in the league."
