The midfielder has insisted that complacency will not creep into the Potters' squad, despite them facing an easier fixture list having met last season's top four already
Tony Pulis' side have been given a thorough examination in their opening eight fixtures, but have lost just twice - against Chelsea and Manchester United.
The Potters posted draws against Arsenal, Liverpool and last season's title winners Manchester City, but the 26-year-old knows that those results will not define the season.
"There's no reason why we should be complacent," Adam told The Sentinel.
"And certainly not if we want to build on what we have done so far this season and what the club did last year.
"It's great to play at places like Manchester United, but they are not the games that decide your season.
"It's games against the likes of Sunderland that are going to influence where we finish."
The Staffordshire outfit slumped to a 4-2 defeat at Old Trafford last time out, but the former Liverpool man has expressed confidence his side will learn from their mistakes.
"We knew it was going to be difficult, but to concede four goals from four crosses was disappointing and hard to take," explained Adam.
"The goals we scored gave us an opportunity to do something in the game, but overall we are disappointed by the goals we conceded. In that second half they had the quality to kill us off.
"To lose a goal a minute before half-time was crucial and then we lose a goal a few seconds after half-time.
"We huffed and puffed in the second half, but we didn't get what we maybe deserved from the game because the first half was probably the best we've played all season, certainly since I've been here.
"But we will learn, take the positives from it and be ready for Sunderland."
