He was speaking ahead of what he described as their "most important game of the season" on Saturday.
The coastal franchise face fierce northern rivals the Bulls at Kings Park on the back of snapping a five-match losing streak against the Force at the weekend.
"For sure [there’s belief]. I mean stranger things have happened," he said after the first Sharks training session since returning from the forgettable Australasian tour.
"I think we’re a team that can play well at home or away from home and I think we’re a team that can deliver under pressure."
The Springbok forward also conceded that their pride was still hurting following their month-long trip, despite the 23-13 triumph in Perth.
"If we didn’t win on the weekend, our season would have probably been over," he said.
"I think we wanted to play good rugby because we hadn’t had the results that we aimed for.
"We wanted to play well to avoid losing six games in a row. I mean none of the guys here have ever lost six games in a row in a Sharks jersey. The guys have too much pride to roll over in that sense."
The Bulls are one of the on form teams of the competition and currently sit second overall, while the Sharks are 10th overall, having been leaders little over a month ago.
They then lost to the Stormers, Cheetahs, Chiefs, Highlanders, and Reds, before the Force win.
Du Plessis admitted everyone was more upbeat following the victory.
"There were positives in the sense that we could have won all the games. But if you look at the black and white, the results are disappointing.
"I don’t think the win itself boosted us, I just think we’re a better team than to not win a game on tour. It was really our aim in that last game to play to our potential, that’s what we did and we won.
"I think everybody feels a bit better and is less depressed now."
The Sharks suffered another injury blow in the last game with star back JP Pietersen breaking his nose.
However, good news for John Plumtree’s side was the potential return of Jannie’s brother Bismarck after almost 10 months out due to knee surgery, while Tendai Mtawarira was also available again after missing the away tour with a calf injury.
"It’s great for him and for the team," Du Plessis said.
"His throwing was brilliant at line-out practice this morning and he fitted in quite well when we scrummed. It’s a bit like getting that old car back that you just know how to drive."
