The Potters have already added six new players to their ranks, including experienced international duo Glen Johnson and Shay Given.
Barcelona starlet Moha El Ouriachi also joined the club at the start of the week and 34-year-old Crouch has become increasingly impressed with the squad manager Mark Hughes is assembling at the Britannia Stadium.
“We are now attracting top-quality signings and top-quality players,” he said.
“I have just finished my fourth season at Stoke City and the difference in the calibre of players, the confidence and the size of the squad has improved no end.
“Each season it seems to improve and this one will be no different… we look forward to having another successful campaign.”
Crouch has been keen to impart his knowledge of the club to the new recruits, realising that as Stoke have established themselves as a top-10 side in England, more internationals will be keen to join.
“I spoke to Glen and obviously I know him well from England and I only had glowing things to say about the club,” Crouch added.
“I have enjoyed my time here since I joined and I know that being able to bring in Glen from such a big club like Liverpool shows how far we have moved on now that he has chose Stoke City.”
