Jack Collison's goal on the stroke of half-time forced the Potters down to 11th with their third loss in four outings but midfielder Adam was not dropping the bundle after the narrow defeat.
"We huffed and we puffed for 90 minutes, but sadly the quality or that cutting edge just wasn't there, and I suppose in the end it just wasn't our day," he told the club's official website.
"It's disappointing, of course it is - nobody wants to lose games. But there is a lot of positives to take from the season so far, there is no doubt about that.
"We have plenty of games to go and we are in a good position in the league, so let's not get too carried away.
"There are 30 points to play for and we will be doing everything we can to get as many of them as possible."
