Port Adelaide will undertake a midseason review aimed at averting the longest losing streak in the AFL club's history.

The Power have lost their past six games to equal the club's longest ever sequence of defeats, in 2006.

And their next three matches are against certain finalists Fremantle, Collingwood and Western Bulldogs.

The grim outlook has prompted Port to review all on-field aspects during their midseason break, playmaker Danyle Pearce said on Monday.

Pearce said the review would occur despite players maintaining "complete faith" in coach Mark Williams' game plan.

"We are going to sit down and re-evaluate everything and just try and adjust in the next half of the year," he said.

Pearce said he was puzzled by Port's plunge, which came after five wins from their initial seven games.

"It ain't fun," he said.

"To lose is really tough and the boys talk about getting Monday depression ... it's not good and we have really got to turn it around and get a win as quick as possible."

Pearce said injuries to key players, including star forward Warren Tredrea and ball magnet Robbie Gray, were not an excuse for the extended series of defeats.

"We are missing about five or six first choice players," he said.

"I think we can put out any 22 (players) and be competitive, it definitely helps having your first choice players out there.

"You can't lie and say it wouldn't help to have the first choice players out there but I can guarantee you, no matter who we put out there, we are going to give a competitive effort for a full four quarters."
