Michael Turner is hoping Norwich can increase their lead on their relegation rivals by beating his former club Sunderland this weekend.
The Canaries are three points clear of the Black Cats and nine points above the drop zone going into the clash at the Stadium of Light.
And the visitors are in a richer vein of form than their opponents, having lost just one of their last six fixtures - the 4-0 defeat at Manchester United - in contrast to a Black Cats side which has lost four of their last five games.
"There's going to be twists and turns between now and the end of the season," Turner said. "We play Sunderland, who are below us, and then we play Wigan, who are in the bottom three at the moment.
"It's an important game for both clubs and we'll be fully focused going into it," said Turner. "It would be nice to keep that cushion after the game.
"We've got big games coming up and I'm sure if we can get through those games in a decent position then we'll be confident."
Turner, who made 77 appearances in three years for the Black Cats before moving to Carrow Road last summer, has combined impressively with Sebastien Bassong in the centre of defence, helping keep nine clean sheets.
"We've been pleased with the amount of clean sheets we've kept," he said.
"That's something we're proud of. If we can keep a few more between now and the end of the season it will put us in a good position.
"Bass (Bassong) has been brilliant this year for us. An experienced player in this league, he's a good defender and it's been nice to play alongside him and keep as many clean sheets as we have done.
"It's obviously a team effort keeping a clean sheet, but it's very pleasing from a back four point of view to keep that many."
