Adam struggled for regular first team football following his move from Liverpool two years ago but he has paid tribute to former boss Tony Pulis and the job he did for the club.
Pulis departed at the end of last season following a total of 10 years - over two spells - at the Britannia Stadium where he helped establish the club as a regular fixture in the Premier League.
"It's a fresh start for everybody and we look forward to it," Adam told Sky Sports News.
"Tony Pulis has done a good job at this club and he deserves the utmost respect and credit.
"If it wasn't for him this club wouldn't be in the Premier League.
"So that's the way it goes and we look forward to a new fresh challenge and the top 10 should be a realistic opportunity for us."
