Mourinho's side travel to the Britannia Stadium 48 hours after Manchester City's 3-0 victory over Crystal Palace drew the defending champions level on points with the Blues.
City are behind the leaders only on goal difference and while Mourinho insists his team will not feel any extra pressure, anything less than victory will hand Manuel Pellegrini's team a major lift heading into the busy Christmas period.
And if they are to reassert their early standing as favourites to be crowned champions, Chelsea must improve on last December's showing at Stoke when individual errors contributed to the home side's 3-2 victory.
But Mourinho is confident his team have learned their lesson and are more than capable of matching Mark Hughes' side.
"We played so well collectively last season but we made two individual mistakes that cost us the game. This is also part of the game," said Mourinho.
"We have to play our football. Our football is the way we believe.”
Meanwhile, Stoke manager Mark Hughes has backed his team to trouble the league leaders’ problems and pounce on any weaknesses.
The Potters boast the second best record in the Premier League against top-half sides after Manchester City and have already beaten Arsenal, Manchester City and Tottenham this season.
Conversely, they are yet to beat anyone in the bottom half of the table, making for a frustratingly inconsistent start for Hughes.
"We're not doing well against the bottom-half sides and that's frustrated us," said Hughes.
"I just feel that when we go up against the so-called bigger teams they are prepared to come out and attack and back their own ability.”
Title hopes dented by Villa draw: Van Gaal
Manchester United manager Louis van Gaal fears that the failure to beat Aston Villa will prove a major blow to their hopes of winning the Premier League title.
United's slim chance of reviving their bid to become English champions suffered a setback on Saturday as they were forced to settle for a 1-1 draw at 10-man Aston Villa.
"We were the better team and that is frustrating when you are the better team and you don't win these kind of games,” said the Dutchman.
"When you want to be a part of the title race you have to win these games.”
