The Warriors have endured a barren start to the season, losing all eight of their Aviva Premiership games.
They have picked up just two points in the process and sit bottom of the standings going into this weekend’s encounter.
Saints are big favourites to pile more misery on Dean Ryan’s men, but Dickinson believes the lack of expectation on the home side’s shoulders makes them a dangerous proposition.
“We know that they’re going to be strong at home,” said the No.8. “It’s not a game we can take lightly.
“It was the same with Newcastle last weekend. We knew it was going to be tough because sometimes the pressure is taken off them so they can cut loose and try to get over the try line.
“It’s going to be difficult.”
Saints beat Newcastle 18-0 at Franklin’s Gardens last weekend, but despite the scoreline the Falcons did manage to cause a few problems.
And Dickinson feels Worcester will take belief from the display of their fellow strugglers.
“It’s going to be interesting,” he said. “I’m sure they’ll look at the Newcastle game and try to take some of the positives from it and reflect it in their own performance.
“They’re a strong outfit as well, especially at home. Some things are going well for them, some things they’re struggling with, but if they can fix them they’re going to be a very tough team to beat.”
