Stoke have splashed £10 million to bring Tottenham striker Peter Crouch to the club, and made further swoop for a forward in Birmingham's Cameron Jerome, and also added another Spurs player in Wilson Palacios.
Crouch has signed a four-year deal with the Potters after struggling for first-team opportunities at Spurs of late. The deal could rise to as much as £12 million dependent on the fulfilment of various clauses.
"These fantastic deals are a statement of this football club's intent," said City's chief executive Tony Scholes after completing the triple transfer swoop.
"The club has made incredible strides forward over the past five years and to attract players of this calibre shows our ambitions as we look to continue that progress this season and beyond that."
Pulis added: "There has been a real buzz of excitement around the city about where this club is going since we reached the FA Cup final and then started our Europa League adventure. These signings certainly add to that great sense of anticipation.
"We now have good options in midfield and up front with these captures add to the experienced additions we also made at the back by bringing in two England defenders Jonathan Woodgate and Matthew Upson earlier in the transfer window.
"Peter has an excellent goalscoring record at the highest level. His goals-per-games ratio for England is remarkable and he scored seven goals in 10 Champions League games for Tottenham last season which gives you an idea of his pedigree."
Honduran international Palacios has also agreed a four year contract. The move was finalised in the countdown to the transfer deadline after Palacios agreed personal terms and underwent a medical.
"This is a fantastic deal for the Football Club because Wilson has proved himself to be a top class performer at the highest level," said City's manager Tony Pulis. "He has a considerable amount of international experience and played a prominent part in getting Tottenham into the Champions League only two years ago.
Jerome completed his deadline-day move to the Britannia Stadium and signed a four-year deal with the Potters after an undisclosed fee was agreed with Blues, after a summer-long chase for him by Pulis, a long-term admirer of the striker.
