Sydney coach Paul Roos is hoping a bunch of newcomers with no knowledge of the club's appalling recent record against Adelaide will help end their run of outs against the Crows on Sunday.

The Swans have lost their last six matches to the Crows, with only Collingwood boasting a current longer winning streak against Sydney.

The harbour city club have lost ten of their last 11 to the Crows including their last five in Adelaide, where they haven't beaten that side in nine years.

Roos was the club's defence coach back then, working under Rodney Eade.

In his final season with Sydney, Roos may not get another chance to break the club's losing streaks against the Crows, unless both teams meet in the finals as they clash only once in the home-and-away schedule.

With the Sydney side for their opening round fixture against St Kilda last weekend containing six newcomers, Roos believed the Swans wouldn't be haunted by their recent failures against Adelaide.

"When you change a coach or when you change a team significantly, the records tend to go out the window because a lot of these guys, at least six, wouldn't know too much about whether we've won or lost and we never really bring it up," Roos told reporters on Wednesday.

"We are a different team to the last six or seven years."

Only five current Sydney players - Jude Bolton, Brett Kirk, Tadhg Kennelly, Adam Goodes and Ryan O'Keefe - were part of the last Sydney team to win in Adelaide.

However, the thumping 105 to 56 victory in round 16 clearly didn't leave much of an impression on O'Keefe.

Asked about his memories of that match, the current Sydney best and fairest said "geez, that's a tough one, that's testing the memory banks.

"I'm not quite sure, it was just good to win."

Like Roos, midfielder O'Keefe hoped the generous infusion of new blood wouldn't carry any stigma of past failures against Adelaide into Sunday's game.

"There's a lot of new players that probably don't know that stat, so I'm not going to tell them," O'Keefe joked.

Roos said there could be a couple of changes to the side narrowly beaten by St Kilda in the opening round.

He was looking at possibly promoting a couple of younger players with midfielder Daniel Hannebery and first round draft pick Gary Rohan among the contenders.

The Sydney coach said Kennelly and Nick Malceski, each of whom picked up a knock against the Saints, would be fine to play this weekend.
