The Baggies are unbeaten in four games, a run which includes a shock victory over Manchester United at Old Trafford, while the Potters have lost their previous three league outings.
Pennant is aware of the threat Steve Clarke's men pose, but hopes West Brom's momentum will be disrupted by the international break as he targets a morale-boosting three points.

"But I'm hoping the international break has put a little block on their momentum and that we can make our own momentum.
"Come Saturday, hopefully we will be fresh and wanting to get started again.
"As soon as we get a goal, no matter how it goes in, if it's 1-0 to Stoke at the Brit it will lift the whole city and we can get going again."
Stoke picked up seven points from their opening four Premier League games under Hughes, but have won none since, and Pennant admits the side have been more tentative in recent weeks.
"We made a great start after the first few games," the 30-year-old continued.
"We have had a couple of dips in the last couple of games, which is unfortunate, and maybe there has been bit of nervousness."
